## What is an XOR gate?

Exclusive OR Gate: It is a digital logic gate that gives a true output when the number of true inputs is odd. A suitable XOR gate can be used as a pseudo-random number generator

### What is the difference between XOR AND 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. In the XOR gate operation, the output is only 1 when only one input is 1.

What is the truth table of XOR gate?

In digital electronics, other logic gates include NOT gates, OR gates, NAND gates, and NOR Gates. Truth tables list the output of a particular digital logic circuit for all the possible combinations of its inputs. The truth table of an XOR gate is given below: The above truth table’s binary operation is known as exclusive OR operation.

#### What is the symbol and truth table of the XOR gate?

Symbol and Truth Table of XOR gate. The Truth Table of 2 input XOR gate. The Boolean expression representing the 2 input XOR gate is written as \$$Y=(A\\bigoplus B)=\\bar{A}.B +A.\\bar{B}\$$

What is an exclusive-OR gate?

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.

## How do you find the Boolean expression for two input logic gates?

The Boolean expression representing the 2 input XOR gate is written as Y = (A⨁B) = ¯A.B+A. ¯B Y = ( A ⨁ B) = A ¯. B + A. B ¯ The Boolean expression for the three-input logic gate is given by Y = A⨁B⨁C= A ¯BC+ ¯AB¯C+ ¯ABC+ABC Y = A ⨁ B ⨁ C = A B C ¯ + A ¯ B C ¯ + A B ¯ C + A B C
