how xor gate works?

XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true.

How is XOR calculated?

To find XOR of more than two numbers, represent all numbers in binary representation, add 0's before if necessary. ... To find each bit of XOR just calculate number of 1's in the corresponding bits. If it is even or zero then that XOR 'ed bit is 0. If it is odd then that XOR 'ed bit is 1. Aug 21, 2014

What is the use of XOR gate?

It is used in simple digital addition circuits which calculate the sum and carry of two (half-adder) or three (full-adder) bit numbers. XOR gates are also used to determine the parity of a binary number, i.e., if the total number of 1's in the number is odd or even.

What is XOR logic?

A connective in logic known as the " exclusive or," or exclusive disjunction. It yields true if exactly one (but not both) of two conditions is true. The XOR operation does not have a standard symbol, but is sometimes denoted (this work) or. (Simpson 1987, pp.
