The Exclusive-OR (EX-OR) operation is widely used in digital circuits. It is not a basic operation and can be performed using the basic gates- AND, OR and NOT or universal gates NAND or NOR. Because of its importance, the standard symbol shown below is used for this operation.
Logical equation of EX-OR gate is written as
Y = A EX-OR B
From the truth table we observe that when both inputs are same (0 or 1) the output is 0, whereas when the inputs are not same (one of them is 0 and the other one is 1) the output is 1.
