Truth Table: The output of an XOR gate is high (1) only when exactly one of its inputs is high (1). If both of an XOR gate's inputs are low (0), or if both of its inputs are high (1), then the output of the XOR gate is low.

What is XOR gate formula?

The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. For example, if we add 1 plus 1 in binary, we expect a two-bit answer, 10 (i.e. 2 in decimal). Since the trailing sum bit in this output is achieved with XOR, the preceding carry bit is calculated with an AND gate.

Is XOR and ex or same?

Introduction to XOR Gate Exclusive OR Gate, also known as EX OR Gate or XOR Gate, is an important digital logic gate, which implements an exclusive or logic i.e., the output is HIGH if and only if one of the inputs is HIGH. If both the inputs are LOW or HIGH, then the output is LOW.

Is XOR and XNOR same?

The XOR output is asserted whenever an odd number of inputs are asserted, and the XNOR is asserted whenever an even number of inputs are asserted: the XOR is an odd detector, and the XNOR an even detector. This very useful property will be exploited in data error detection circuits discussed later.

Why XOR is called exclusive or?

It gains the name "exclusive or" because the meaning of "or" is ambiguous when both operands are true; the exclusive or operator excludes that case. This is sometimes thought of as "one or the other but not both". This could be written as "A or B, but not, A and B".

What is XOR operation?

(eXclusive OR) A Boolean logic operation that is widely used in cryptography as well as in generating parity bits for error checking and fault tolerance. XOR compares two input bits and generates one output bit. The logic is simple. If the bits are the same, the result is 0. If the bits are different, the result is 1.

What is 2 input XOR gate?

2-input Ex-OR gate This is a simple form of the hybrid gate XOR. In this type of XOR gate, there are only two input values and an output value. There are 22=4 possible combinations of inputs. The output level is high when both inputs are set to a different logic level.

What is XOR of two numbers?

XOR or eXclusive OR is a logical operation that compares the input values (bits) and generates the output value (bit). The exclusive OR logic is very simple. If the input values are the same, the output is 0 (or false). If the input values are different, the result is 1 (or true).

How XOR is formed?

The Exclusive-OR gate or XOR gate is achieved by combining standard logic gates together. XOR gate is used extensively in error detection circuits, computational logic comparators and arithmetic logic circuits.

What type of gate is XOR?

XOR gate (sometimes called EOR, EXOR, and pronounced as Exclusive OR) is a digital logic gate that results in true (either 1 or HIGH) output when the number of true inputs is an odd count. An XOR gate implements an exclusive OR, i.e., a true output result if one, and only one, of the gate inputs, is true.

What is the opposite of XOR?

The XOR function is only true if just one (and only one) of the input values is true, and false otherwise. XOR stands for eXclusive OR. As can be seen, the output values of XNOR are simply the inverse of the corresponding output values of XOR.

What is a XOR 1?

XOR is a logical operator that works on bits. Let's denote it by ^ . If the two bits it takes as input are the same, the result is 0 , otherwise it is 1 . This implements an exclusive or operation, i.e. exactly one argument has to be 1 for the final result to be 1 .

What are the 3 types of logic gates?

All digital systems can be constructed by only three basic logic gates. These basic gates are called the AND gate, the OR gate, and the NOT gate. Some textbooks also include the NAND gate, the NOR gate and the EOR gate as the members of the family of basic logic gates.

What are XOR and XNOR gates called?

Exclusive-NOR gate or XNOR gate is formed by combining the Exclusive-OR gate (XOR gate) and the NOT gate. On analysing the XNOR truth table, we understand that the output is similar to the standard NOR gate except that the output of the XNOR gate is high when both inputs are high.

How do you convert XOR to XNOR?

The XOR operation of inputs A and B is A ⊕ B; therefore, XNOR operation those inputs will be (A + B) ̅. That means the output of the XOR gate is inverted in the XNOR gate.

Can XOR gate have 3 inputs?

For 3 or more inputs, the XOR gate has a value of 1when there is an odd number of 1's in the inputs, otherwise, it is a 0. Notice also that the truth tables for the 3-input XOR and XNOR gates are identical.

Is XOR same as addition?

It is called "parity" addition or "XOR" (The word XOR originated from exclusive-OR). We still call it addition because this operation has many properties in common with standard decimal (or binary) addition: it is commutative and associative, and "adding" zero to a number doesn't change the number.

How do you remember XOR?

One way to think about it is that XOR (eXclusive-OR) is exclusively OR and not AND. Another way is that XOR is exclusive in that you can only pick one of the options: i.e. "You can't have your cake and eat it too."

Is XOR a universal gate?

You can't derive an OR (or AND, NOR, NAND) gate from only XOR (or XNOR) gates, because they are not universal gates.

What is XOR of three numbers?

The task is to count the numbers of pairs of integers A and B such that A + B + N = A ^ B ^ N and A and B are less than N. So (0, 0), (0, 1) and (1, 0) are the required pairs. So the output is 3.
