The post What is the Augmented Reality? appeared first on EE-Vibes.

]]>What is the Augmented Reality? The Augmented Reality (AR) is a technology that allows users to interact with digital content in the real world. AR can be used for a variety of purposes, including education, gaming, and communication.

There are two main types of AR: marker-based and markerless. Marker-based AR uses physical markers to track the user’s location and display digital content. Markerless AR uses the user’s GPS location to track the user’s location and display digital content.

Here are few examples of augmented reality. That are:

– Pokémon GO

– IKEA Place

– Google Translate

– Snapchat Lenses

– Sky Guide AR

– Anatomy AR

These are just a few examples of augmented reality in use today. As the technology continues to develop, we can expect even more innovative and exciting applications for augmented reality! We can’t wait to see what the future holds for this amazing technology.

Augmented reality (AR) is an enhanced version of the physical world that is augmented by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, augmented reality is a composite view of the real world and its virtual enhancement. This technological innovation has been used in various fields such as gaming, education, advertising and even medicine. Let’s take a look at some of the most popular augmented reality examples that are being used today.

– Pokémon GO: This augmented reality game became an instant sensation when it was released in 2016. It allows players to catch, battle and train virtual Pokémon characters that appear in the real world.

– IKEA Place: This app from IKEA lets you place virtual furniture in your home to see how it would look before you buy it. You can even choose different colors and styles to find the perfect piece for your space.

– Google Translate: This augmented reality feature from Google allows you to point your phone’s camera at a sign or piece of text in another language and see the translation in real-time. It’s a handy tool for travelers who need a little help understanding what they’re seeing.

– Snapchat Lenses: These fun augmented reality filters can change your appearance in a variety of ways, from adding animal ears and a nose to your face to turning you into a walking rainbow.

– Sky Guide AR: This app uses augmented reality to help you identify stars, constellations and other celestial bodies in the night sky. Just point your phone up at the sky and let the app do the rest.

– Anatomy AR: This augmented reality app lets you see inside the human body in a way that is not possible with traditional textbooks. You can view different organs and systems, and even see how they work together.

Augmented reality (AR) is a technology that overlays digital content on the real world. You can experience AR through your smartphone, tablet, or computer. To see AR content, you’ll need to download an app that supports AR. Once you have the app, you can point your device at a real-world object to see digital content appear on top of it.

AR apps are created using ARKit and ARCore, two software development kits (SDKs) from Apple and Google respectively. These SDKs allow developers to create AR experiences for their apps. If you’re a developer and you’re interested in creating an AR app, you can learn more about ARKit and ARCore on the Apple Developer website and the Google Developers website.

AR is used for a variety of purposes, including gaming, education, productivity, and social media. There are many different types of AR experiences that you can have. Some AR experiences are passive, meaning that you can look at them but you don’t interact with them.

Other AR experiences are interactive, meaning that you can interact with the digital content that appears in the real world. One of the most popular AR games is Pokémon GO. In this game, players use their smartphones to catch virtual Pokémon that appear in the real world.

Pokémon GO is a great example of how AR can be used to create an immersive gaming experience. AR is also being used in education. For example, the app “ChemCaper” allows students to learn about chemistry by playing a game set in a virtual world. And the app “Solar System Explorer” allows users to explore the solar system by pointing their device at the sky.

There are also AR productivity apps that can help you with tasks like taking notes, managing your calendar, and more. And there are AR social media apps that allow you to share your experiences with your friends and family. AR is an exciting new technology with a lot of potential. We’re just beginning to scratch the surface of what’s possible with AR.

As more developers create AR apps, we’ll see even more amazing and innovative uses for this technology. How does augmented reality work? How can I use augmented reality?

]]>What are the Maxima and Minima of a Function? The maxima of a function is the highest point on the graph of the function. In other words, it is the point at which the function reaches its maximum value.

The maxima of a function can be found by taking its derivative and setting it equal to zero. This will give you the x-coordinate of the maxima. You can then plug this x-coordinate back into the original function to find the y-coordinate of the maxima.

The maxima of a function can also be found by looking at its graph. To do this, you need to find the points where the graph changes from concave up to concave down. These points will be the maxima of the function.

You can also use the second derivative test to find the maxima of a function. This test involves taking the second derivative of the function and setting it equal to zero. If the second derivative is positive at this point, then the point is a local maxima. If the second derivative is negative at this point, then the point is a local minima.

The second derivative test can be used to find both the local maxima and the global maxima of a function. Global maxima are the highest points on the graph of the function, while local maxima are the highest points within a certain region.

The maxima and minima of a function can also be found by looking at its graph. To find the maxima, you need to find the points where the graph changes from concave up to concave down. These points will be the maxima of the function.

To find the global maxima, you need to take the derivative of the function and set it equal to zero. This will give you the x-coordinate of the maxima. You can then plug this x-coordinate back into the original function to find the y-coordinate of the maxima.

The second derivative test can also be used to find saddle points. Saddle points are points where the graph of the function changes from concave up to concave down.

To find saddle points, you need to take the second derivative of the function and set it equal to zero. If the second derivative is positive at this point, then the point is a local maxima. If the second derivative is negative at this point, then the point is a local minima. Saddle points are important because they can be used to optimize functions.

To optimize a function, you need to find the point where the function reaches its maximum or minimum value. The maxima of a function is the highest point on the graph of the function, while the minima is the lowest point on the graph of the function. To find the maxima of a function, you need to take its derivative and set it equal to zero. This will give you the x-coordinate of the maxima. You can then plug this x-coordinate back into the original function to find the y-coordinate of the maxima.

The minima of a function can be found by taking the derivative of the function and setting it equal to zero. This will give you the x-coordinate of the minima. You can then plug this x-coordinate back into the original function to find the y-coordinate of the minima.

The second derivative test can also be used to find saddle points. Saddle points are points where the graph of the function changes from concave up to concave down.

To find the minimum and maximum values of a polynomial, you need to take the derivative of the polynomial. The derivative will tell you how the function is changing at that point. If the derivative is positive, then the function is increasing. If the derivative is negative, then the function is decreasing. To find the minimum value, you want to find the point where the derivative is zero. To find the maximum value, you want to find the point where the derivative is undefined.

You can also use calculus to find the minimum and maximum values of a polynomial. Calculus is a branch of mathematics that deals with derivatives and integrals. To find the minimum and maximum values of a polynomial, you need to take the derivative of the polynomial. The derivative will tell you how the function is changing at that point. If the derivative is positive, then the function is increasing. If the derivative is negative, then the function is decreasing. To find the minimum value, you want to find the point where the derivative is zero. To find the maximum value, you want to find the point where the derivative is undefined.

We will use the function:

f(x) = x^(−sin(x))

The domain of this function is all real numbers. The range is all positive real numbers. To find the critical points of this function, we take the derivative:

f ‘(x) = -cos(x)*x^(-sin(x)) – sin(x)*ln(x)*x^(-sin(x))

Setting this equal to zero and solving for x gives us:

cos(x) = 0 OR sin(x)*ln(x) = 0

Thus, the critical points are: x=0, π/n, (n is any integer).

To find the maxima and minima, we need to look at the second derivative:

f ”(x) = sin(x)*cos(x)*x^(-sin(x)) – ln(x)*cos(x)*x^(-sin(x)) – sin(x)*ln(x)^(−sin(x)) – sin(x)*ln(x)*(-sin(x))*x^(-sin(x)-

The second derivative will be zero at the same points as the first derivative. However, we can also have a critical point where the second derivative is undefined. This will happen when:

sin(x)*ln(x) = 0 AND cos(x) = 0

This can only happen at x=0. To test if this is a maxima or minima, we take the limit as x approaches zero from both sides. We get:

lim f ‘(x) = lim -cos(x)*x^(-sin(x)) – sin(x)*ln(x)*x^(-sin(x))

= -∞ + 0

= -∞ (from the left) OR 0−∞ (from the right)

Thus, we have a minimum at x=0.

Now, we need to test the other critical points to see if they are maxima or minima. We do this by plugging in the values of x and taking the second derivative. If the second derivative is positive, it is a minimum. If the second derivative is negative, it is a maximum. If the second derivative is undefined, we take the limit as x approaches the critical point from both sides to see if it is a maxima or minima.

For x=π/n:

f ”(x) = sin(x)*cos(x)*x^(-sin(x)) – ln(x)*cos(x)*x^(-sin(x)) – sin(x)*ln(x)^(−sin(x)) – sin(x)*ln(x)*(-sin(x))*x^(-sin(x)-

= 0 * cos((π/n)) * (π/n) ^ (-sin((π/n))) – ln((π/n)) * cos((π/n)) * (π/n) ^ (-sin((π/n))) – sin((π/n)) * ln((π/n))^(-sin((π/n))) – sin(x)*ln(x)*(-sin(x))*x^(-sin(x)-

= 0

Thus, we have a minimum at x=π/n.

For x=(n is any integer):

f ”(x) = sin(x)*cos(x)*x^(-sin(x)) – ln(x)*cos(x)*x^(-sin(x)) – sin(x)*ln(x)^(−sin(x)) – sin(x)*ln(x)*(-sin(x))*x^(-sin(x)-

= 0 * cos((n is any integer)) * (n is any integer) ^ (-sin((n is any integer))) – ln((n is any integer)) * cos((n is any integer)) * (n is any integer) ^ (-sin((n is any integer))) – sin((n is any integer)) * ln((n is any integer))^(-sin((n is any integer))) – sin(x)*ln(x)*(-sin(x))*x^(-sin(x)-

= 0

Thus, we have a minimum at x=(n is any integer).

We have now found all the maxima and minima of the function. We have one maximum at x=0 and an infinite number of minima at π/n and (n is any integer).

]]>How to Determine the Overflow of Signed and Unsigned Numbers?. Numbers represented in computer system have always have a specific range. It depends on how many bits your system process. Some systems are 32 bits while other are 64-bits. With the advancement in technology we have now** l**arger bits processing systems. But they have limited range of numbers they can represent. Overflow refers to the condition when the given bits can not represent the given number. It means that number needs more bits for its representation. There is another situation where the number is small enough and not representable according to the given pattern of numbers. This is called **underflow. **

How to define and determine overflow of unsigned numbers? Unsigned integers are those integers that are used for representing the magnitudes. They do not need any sign for their representation because these quantities are always positive. Such quantities are used for representing the quantities such as addresses of memory locations, and ASCII characters codes.

The largest value that can be stores in 8-bits is (11111111) FFH that is 255 in decimal. Similarly in a word this value becomes (FFFFH) or 65535. Now the question arises how these values are determined. The general formula is to calculate (2^n)-1. Where n is the given number of bits for which you want to determine the range. For example, for 8 bits we have 2^8-1= 256-1=255. 1 is subtracted because 0 is included in the range. So there are total 256 numbers and the range for 8-bit numbers is 0 to 255.

The same formula can be extended for any number of bits. If the least significant bit (LSB) of a binary combination is zero then the number is **even **and if it is one (1) then the number is **odd. **

How to define and determine overflow of signed numbers? Unsigned Integers are little bit tricky to understand. All we need is little bit more attention for understanding them. Whenever a number is treated as signed then it be either positive or negative. In binary representation, the most significant bit (MSB) is reserved for representing the sign. If MSB=0 then the number is positive and if MSB=1, then the number is negative.

In order to determine the range of signed numbers consider the following example of 8 bit numbers

For 8 bit numbers, msb is reserved for sign so all bits will be equal to 1( 01111111) while representing the largest positive number. The weighted binary sum of this combination gives

The smallest negative number is 1000 0000 means all other bits are equal to zero and only sign bit is set high.

The negative numbers are usually stored as 2’s compliment or by taking the one’s compliment and then adding 1 in it.

Consider we want to store -3 in computer

first find its binary combination in 8 bits that is

0000 0011

take one’s compliment (For this invert all bits) so

1’s compliment is: 1111 1100

and then add 1 in it.

1111 1100

+1

_________________

1111 1101

_________________

so in this way any number can be stored.

The range of n bit signed numbers is determines as (2^n)/2 -1

In case of 8-bit numbers

2^8=256

2^8/2=128

128-1=127

so the numbers lie in between -128 to 127. If a number that has value out of this range then it will cause **overflow**. E.g., if there is an addition of two numbers that fall within the range. Now their resultant is some number that does not lie within this range then it will show overflow. Status flag is used for representing the overflow.

There can be both types of overflow, signed overflow and unsigned overflow. It depends how the numbers are treated.

Consider the following example again

1111 1111 1111 1111

+0000 0000 0000 0001

____________________

1 0000 0000 0000 0000

____________________

if both numbers are treated as unsigned numbers , then the first combination gives (65535) and second combination is equal to 1. Adding both of them will result 65536 that is out of range of unsigned integers (as 65535 is the largest possible value). **Here unsigned overflow occurred. **

If both numbers are treated as signed then the first number (1111 1111 1111 1111) is equal to -1

and the second number is (+1)

so if we add (-1)+(1) then the resultant is equal to zero which is true as it matches with the result (1 0000 0000 0000 0000). So **no signed overflow occurred. **

0111 1111 1111 1111

0111 1111 1111 1111 +

_________________

1111 1111 1111 1110

_________________

If the above number is treated as unsigned then its value is (32767). As both numbers are same so when we add them we get, 131068 which falls within the range of unsigned integers. So, **no unsigned overflow **occurred.

If we treat both of them as signed then both are positive numbers as msb=0. But the resultant has msb =1 which shows some negative number. Although the addition of two positive numbers can never be a negative one so **signed overflow **occurred. In terms of magnitude the resultant is 131068 that exceeds the value of positive numbers of 16-bit combination (32767).

From above examples it is concluded that signed overflow occurs **during addition** when there is a carry out of MSB. Which means the represented number is greater than the available bits or biggest numbers FFH for 8-bits and FFFFH for 16 bits. **During subtraction **the unsigned overflow occurs when there is a borrow into the MSB. In this case the correct answer is actually smaller than 0.

During addition, if both numbers that you are adding are positive but the resultant is negative, then signed overflow occurs. When numbers are of different signs during addition, then signed overflow is impossible. As A-B or -A+B will always be smaller than the available bits. While in subtraction, if the resultant has different sign as expected then it will cause overflow.

Two flags are used for indicating the unsigned overflow (Carry flag CF=1) and (overflow flag OF=1) for signed overflow. These two flags are present in status register of computer.

There is an easy way to understand either there is overflow or not. If there is a carry in into the MSB and a carry out from the MSB then there will be no overflow. But if there a carry in into the MSB but not a carry out or if there is a carry out from the MSB but not a carry in then the overflow occurs.

Cheapest lithium marine batteries are available in the market and they are very popular among boat owners. Many people use these batteries for their boats because they are cheaper than other types of batteries. Lithium marine batteries have many advantages over lead-acid batteries and this is the reason why they are becoming more popular. In this article, we will discuss how to improve the efficiency of cheapest lithium batteries.

One way to improve the efficiency of cheapest lithium batteries is by using a battery charger. Chargers help to keep the battery in good condition and they also help to prolong the life of the battery. You should always use a charger that is designed for lithium batteries. Another way to improve the efficiency of these batteries is by using a battery monitor. A battery monitor will help you to see the current status of the battery and it will also help you to know when the battery needs to be charged.

You can also improve the efficiency of cheapest lithium batteries by using a power management system. A power management system helps to control the charging and discharging of the battery. This system can help to prolong the life of the battery and it can also help to improve the efficiency of the battery. You should always use a power management system that is designed for lithium batteries.

Another was is by using a solar charger. Solar chargers are very effective in charging the battery and they also help to prolong the life of the battery. You should always use a solar charger that is designed for lithium batteries.

]]>The post How to Design a Four bit Adder-Subtractor Circuit? appeared first on EE-Vibes.

]]>In this article you will learn about how to design a four bit adder-subtractor circuit? Every Digital Computer should always execute two arithmetic Operations: addition & subtraction. Multiplication & Division operations become simple if both of these tasks are implemented properly (Multiplication is equivalent to repeated addition, whereas division is equivalent to repeated subtraction). Take into account the process of trying to add multiple binary numbers, that is the basic operations executed by a computer system. The four fundamental addition operations for multiple binary numbers which are single bit, are as follows:

- 0 + 1 = 1
- 1 + 0 = 1
- 0 + 0 = 0
- 1 + 1 = (Carry)1 0

Every Digital Computer should always execute two arithmetic Operations: Every binary addition during first 3 operations yields a total of one bit, namely, either zero or one. However, the output of the 4th addition operation (with inputs of One and one) is 2 binary numbers. here lower significant bit usually referred to as ‘Sum Bit,’ whereas higher significant bit has been referred to as ‘Carry Bit.’

The full adder is an added that takes three inputs &generates two outputs as a result. The first 2 inputs typically A & B, with the third being a C-IN input carry. Output carry generally labelled as C-OUT, whereas normal output labelled as S, that stands for SUM.

A half adder is a type of combinational arithmetic circuitry that uses two numbers addition and outputs an S, sum bit, as well as a C, carry but. The S (sum bit) is the result of the XORing of A & B, and also the C (carry bit) is the ANDing of A & B, if A & B, seem to be input bits.

Binary Adder-Subtractor comprises a digital circuit that can perform basic arithmetic of binary integers in the same circuit. The binary result of a control signal determines the operation to be executed. It’s among the ALU‘s, arithmetic logic unit elements

XOR Gate, Full Adder, and Binary Addition & Subtraction, are all prerequisites for this circuit.

Designing: A single basic binary adder may do both addition & subtraction tasks. As illustrated in the diagram underneath, a binary circuit may be created by combining an Ex-OR gate alongside every full adder. 4-bit parallel adder and 4-bit parallel subtractor shown below has multiple 4 bit inputs labelled ‘A3 A2 A1 A0’ & ‘B3 B2 B1 B0’.

The carry input of the of the full adder’s least significant bit is linked to the mode input control line labelled as k. The kind of execution, either addition and otherwise subtraction, is determined by such a control line.

If k equals to 1, circuit is just a subtractor, but when k equals to zero, it is then converted to an adder. XOR gate has 2 inputs, only one of which being Linked to the B, the other to the input k. Whenever k = 0, B Ex-ORed 0 results in B. Next, full adders perform addition of B & A with carry input 0, resulting in addition operation.

- If M = 1, the B Ex-ORed Zero produces the B complement, as well as the carry input becomes 1. As a result, inputs of complemented B are added with A, then One is added via input carry, nothing more than an operation of 2’s complement. As a result, the operation of subtraction is carried out.
- First Adder: The 1st full adder includes a control line as one of its direct inputs (input carry Cin).
- Second Adder: Within full adder, the input A0, A’s least significant bit, is explicitly input.
- Third Adder: The XORed of k and B0 is the 3rd input. Sum or Difference, referred to as S0 and Carry (C0) are the outputs generated.

Finally, as being one of the outputs of the 2nd full adder, C0 gets serially passed. The sum or difference S0 gets stored as the sum or difference’s least significant bit. A1, A2, & A3 constitute as direct inputs to the 2nd, 3rd, and 4th full adders, respectively. The 3rd input would be the B1, B2, B3 XORed K to the 2nd, 3rd, and 4th full adders. Carry C1 and C2 get serially passed as inputs towards the consecutive full adder. C3 will become the sum or difference’s total carry. S1, S2, and S3 are recorded in order to build the outcome with S0.We employ n full adders to create an n-bit adder-subtractor.

First of all, what is a binary adder? It is a type of digital circuit that usually adds binary numbers using logic gates. In ordinary addition of binary numbers we use only two bits at a time in order to add them i.e we add 1 and 0 at a time or we add 0 and 1 only at a time, moreover we add 1 and 1 or 0 and 0 at a time. But in this system we directly add the whole binary number to another whole binary number at a time with the help of arithmetic circuits. There are two types of adders which are full-adders and half-adders as discussed below:

It is used for the addition of significant digits.(carry)

The logic gates which are used in Binary full-adders are And gate, OR gate and EXOR gate. In practical life, the applications of full adders are that they are used in digital processors.

It is used for addition of Least significant digits. The logic gates involved in half adders are EX OR gate and AND gate. Half adders are practically used in digital measuring devices like calculators.

For reading more about Full-adder and Half-adders check:

**Subtractor Circuit:**

It is a digital circuit used for subtraction of binary numbers using logic gates. In this we add (2’s compliment and 1) on the number from to be subtracted. For example we have to subtract A from B, We do A+ (2’s compliment of B+1). Two types: Half-subtractor and Full-subtractor.

It is the circuit in which subtraction of two bits is done by borrowing. There are three inputs and two outputs.

The half subtractor is used to subtract two binary . There are two inputs and two outputs on this device. This circuit is used to subtract two binary values, A and B, that are both single bits. The half subtractor has two output states: ‘diff’ and ‘borrow.’

Basically it is a digital circuit which does both addition as well as subtraction itself. This circuit works using an EX-OR gate, binary addition and subtraction, Full adder.

We will need four full adders. Supplying them inputs respectively, A0, A1, A2, A3 for first adder, second adder, third adder, and fourth adder. Now the second input for adders would be output of EX-OR gates, Same as input A, There would be attached four EX-OR gates with all adders respectively. As we all know that this EX-OR gate will have two inputs. The first input of this EX-OR gate would be named as B, and as done previously

We will name B0, B1, B2, B3 respectively. And the second input to this EX-OR gate is what we are providing it to be ‘M’ input which would be the second input of the EX-OR gates and which would be same for all EX-OR gates. This M will decide whether we are performing addition operation or subtraction operation. And Beside all this the 3^{rd} input we are going to provide is to be known as the carry or borrow, which would be the same ‘M’. In case of addition it would be carry while in case of subtraction it would be borrow.

So in addition operation this carry is given to the full-adder and the full adder output would be sum S0 (at the first adder) and carry C1(from the first full adder). And the carry generated would be propagated to the next full adder. Similarly, next full adder will generate sum and generate carry to next full adder, and so on to all full adders.

But if it would be a subtraction operation then instead of sum we would be having difference and instead of carry we would be having borrow. So this is our circuit.

Lets see its working with an example:

If we provide ‘M’ to be ‘0’ all the EX-OR gates will have one fixed input ‘0’ and carry ‘C0’ would also be ‘0’, If we talk about another input of EX-OR gate that is B, So as per truth table of XOR gate if we XOR any value with 0 then it would be same as that value. So as per truth table or XOR ‘0’ XOR ‘ B0’ we would be having output ‘0’. O XOR b1 we would be having B2, 0 XOR B3 we would be having B3. In simple input to this XOR gate would be B. On the other hand on carry side Carry would be 0 because we had fixed M as 0. So in a nutshell the formula for Sum becomes: M=A+B (by taking M=0).

Now considering M to be 1, So all inputs of XOR would be 1, as per truth table of XOR if we XOR any value with 1 it would always be compliment of that value. So B0 XOR 1 would be B0’(B0 compliment). B XOR 1 would be B1’ and so on.

so if we provide M to be 1 then input to full adder becomes compliment of B So it becomes A + B’ + 1. Which is nothing but our subtraction. So formula for subtraction is M= A+B’+1 by (taking value of M 1)

Consider the advanced version of 4-bit adder-subtractor circuit which comes with carry (C) bit and overflow (V) bit. The role of C pin is to determine the overflow in the unsigned numbers. If C=1, then there is a carry out in case of addition (indicating unsigned overflow) or a borrow in during subtraction.

V bit is used for indicating the signed overflow. Let us consider the case for understanding the concept of overflow. Basically overflow occurs when we add or subtract two n-bit numbers and the resultant is of n+1 bit.

We know that the range of 4-bit unsigned numbers is 0 to 15 and range of 4-bit signed numbers is -8 to 7. For getting the idea of how to determine the range, check this link.

Now, assume the case when we want to add two numbers A=1000, B=0101. If we treat both numbers as unsigned, then A is equal to 8 in decimal and B= 5 in decimal. To see how we perform number systems conversion, check the **link. **

If you will perform A+B bit wise

1000

0101 +

_________

1101

_________

There will be no carry out. Now if you convert this binary to decimal you will get the result is equal to 13. So unsigned overflow did not occur. Now consider the other case when A=1001 (9) and B=0111 (6). When you will perform bit wise addition, you will see there is a carry out (C) from the last full-adder. Which will indicate the unsigned overflow. Since 9+7=16 which is actually out of range of 4-bit numbers. If you will consider the 5-bits (10000) including the carry bit C, then the result is correct otherwise 4-bit sum (0000) shows the wrong result. V=0 in this case.

Now again assume same inputs A=1001 and B=0111. But this time we are going to perform the subtraction A-B considering A and B as signed numbers. As we know that when we treat numbers as signed, the MSB represents the sign of the number. If MSB=1 then the bit combination represents the negative number and when MSB=0 then a positive number is stored. So in our case A=-ve number and B=+ve (7).

We can see what number A represents by taking its 2’s complement.

1112

1001 –

________

___0111__

so it actually represents -7. When you will perform subtraction using the adder subtractor circuit, you will see V=1 and also C=1. This actually indicates there was a borrow in during subtraction (while treating them as unsigned numbers) and V=1 which actually shows a signed overflow occurred as explained in my video lecture given below. Since (-7)-(+7)=-14 which is actually out of range of 4-bit numbers. That’s why you will need total 5-bits for representing the correct answer.

]]>Explain RC Coupled Transistor Amplifier. The RC coupled transistor amplifier is one of the most popular types of amplifier circuits. It is widely used in a variety of applications such as audio amplifiers, radio transmitters and receivers. The circuit consists of two transistors, a resistor and a capacitor connected in series. The first transistor acts as an input stage and the second transistor acts as an output stage.

The input signal is applied to the base of the first transistor. This transistor amplifies the signal and applies it to the base of the second transistor. The second transistor amplifies the signal further and applies it to the load resistance. The capacitor couples the two stages together and allows only the ac component of the signal to be amplified. The resistor provides DC biasing to the transistors.

The circuit shown in Figure 1 is a common emitter RC coupled amplifier using NPN transistors.

Also check:

The input signal is applied to the base of Q1 via R1. Q1 amplifies the signal and applies it to the base of Q2 via C1. Q2 amplifies the signal further and applies it to the load resistance, RL. C2 couples the two stages together and allows only the ac component of the signal to be amplified. R2 provides DC biasing to the transistors.

The circuit shown in Figure 2 is a common collector RC coupled amplifier using PNP transistors.

The input signal is applied to the base of Q1 via R1. Q1 amplifies the signal and applies it to the base of Q2 via C1. Q2 amplifies the signal further and applies it to the load resistance, RL. C2 couples the two stages together and allows only the ac component of the signal to be amplified. R2 provides DC biasing to the transistors.

The main advantage of the RC coupled amplifier is that it has a relatively high input impedance and a low output impedance. This makes it ideal for use in applications where it is necessary to match the impedance of the amplifier to the impedance of the load. The RC coupled amplifier is also relatively simple to construct and is therefore a popular choice for many applications.

The voltage gain of an RC coupled amplifier is determined by the ratio of the collector resistor to the base resistor. The higher the ratio, the higher the voltage gain. For example, if the collector resistor is 10 times the value of the base resistor, the voltage gain will be 10.

The bandwidth of a RC coupled amplifier is determined by the value of the capacitors used in the circuit. The larger the capacitor, the wider the bandwidth. The bandwidth is also affected by the resistor values in the circuit. Higher resistor values will result in a narrower bandwidth. The bandwidth can also be increased by adding additional capacitors to the circuit.

The bandwidth of an RC circuit is determined by the time constant, which is the product of the resistance and capacitance. The time constant is a measure of the time it takes for the voltage to ramp up or down in response to a change in current. The larger the time constant, the slower the voltage will change in response to a change in current, and the smaller the bandwidth. The time constant is also a measure of the frequency at which the voltage will start to roll off. The higher the time constant, the lower the frequency at which the voltage will start to roll off.

To calculate the bandwidth of an RC circuit, you need to know the value of the resistance and capacitance, and the time constant. The time constant is the product of the resistance and capacitance.

The bandwidth of an RC circuit is given by:

Bandwidth = 1 / (2 * pi * time constant)

where:

pi is 3.14159…

time constant is the product of the resistance and capacitance.

For example, if the resistance is 10 ohms and the capacitance is 0.1 Farads, then the time constant would be 1 second. The bandwidth would be:

Bandwidth = 1 / (2 * pi * 1)

Bandwidth = 1 / (6.283)

Bandwidth = 0.16 Hz

This means that the voltage will start to roll off at frequencies below 0.16 Hz.

If you know the bandwidth, you can calculate the time constant. The time constant is the inverse of the bandwidth.

Time constant = 1 / bandwidth

For example, if the bandwidth is 0.1 Hz, then the time constant would be:

Time constant = 1 / 0.1

Time constant = 10 seconds

This means that it would take 10 seconds for the voltage to ramp up or down in response to a change in current.

If you know the time constant, you can calculate the resistance and capacitance. The resistance is given by:

Resistance = time constant / capacitance

In order to display this information on devices screens, LCDs, or seven segments they need to be converted into the ASCII format.

First a packed BCD number is converted into unpacked BCD, then it is masked with 30H and finally it is converted into ASCII.

How to perform Packed **BCD** to **ASCII** conversion and vice versa? Binary Coded Decimal is an encoding system in which decimal numbers from 0 to 9 are represented in binary form.

In bytes orientation, Binary Coded Decimal is divided into two systems which are following:

Unpacked BCD is an encoding system in which every digit has its own byte. This system is commonly used in the modern computers to deal the data accurately.

Example: Unpacked BCD of 12 = 00000001 & 00000010

Unpacked BCD of 27 = 00000010 & 00000111

Also check:

Packed BCD is an encoding system in which two digits are encoded in a byte, one digit is the upper nibble and other digit is the lower nibble.

Example: Packed BCD of 12 = 00010010

Packed BCD of 27 = 00100111

In computers, all the information is represented in 0s and 1s, binary pattern must assign letters and other symbols or characters. Standard representation of this pattern was established in 1960 who names as ASCII which is stands for American Standard Code for Information Interchange. The great advantage of this system is that it is used by most of the computers therefore information is shared with other computers easily. ASCII code assign binary pattern from 0 to 9 in all alphabets of English both in uppercase and lower case. ASCII system needs seven bits to represent a code.

Example: 100 0010 = B

110 0011 = C

Zero is placed in the most significant bit position to make it eight-bit code. ASCII code from 0 to 9:

** **Many new microcontrollers have Real Time Clock (RTC), where the data is stored even the power is on or off. These microcontrollers provide data in BCD. Therefore, to display their data on screen we need to convert it into ASCII.

Real Time Clock (RTC) provides the time (hours: minutes: seconds) and the date (year: month: day) continuously regardless of the power is on or off in the modern microcontrollers. However, data is provided in in packed BCD format. To represent this data on screen or printed by the printer, it must be in ASCII format. So, we need to convert packed BCD to unpacked BCD first then further convert into ASCII.

For Example:

Packed BCD |
Unpacked BCD |
ASCII |

35H
0011 0101 |
03H & 05H
0000 0011 & 0000 0101 |
33H & 35H
0011 0011 & 0011 0101 |

49H
0100 1001 |
04H & 09H
0000 0100 & 0000 1001 |
34H & 39H
0011 0100 & 0011 1001 |

Here is the code first

Output on MPLAB

** **This is the reverse process of the packed BCD to ASCII. First, we need to convert ASCII into unpacked BCD and then unpacked is converted into packed BCD.

For Example:

ASCII |
Unpacked BCD |
Packed BCD |

37H & 38H
0011 0111 & 0011 1000 |
07H & 08H
0000 0111 & 0000 1000 |
78H
0111 1000 |

39H & 31H
0011 1001 & 0011 0001 |
09H & 01H
0000 1001 & 0000 0001 |
91H
1001 0001 |
