# Question: What is the purpose of XOR gate?

Contents

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 1s in the number is odd or even.

## What is the purpose of exclusive gates such as the XOR and XNOR?

Another way to explain an XOR gate is as follows: The output is HIGH if the inputs are different; if the inputs are the same, the output is LOW. The XOR gate has a lesser-known cousin called the XNOR gate. An XNOR gate is an XOR gate whose output is inverted....Electronics Logic Gates: XOR and XNOR Gates.Input AInput BOutput1011102 more rows

## What is the role of XOR gate in parity generation?

The XOR, XNOR, Even Parity, and Odd Parity gates each compute the respective function of the inputs, and emit the result on the output. The XNOR gate will emit 1 only when there is not exactly one 1 input, while the Even Parity gate will emit 1 if there are an even number of 1 inputs.

## How do XOR gates work?

An XOR gate (sometimes referred to by its extended name, Exclusive OR gate) is a digital logic gate with two or more inputs and one output that performs exclusive disjunction. The output of an XOR gate is true only when exactly one of its inputs is true....XOR Gate.Input AInput BOutputtruetruefalse3 more rows

## Why XOR gate is called exclusive?

An XOR gate (also known as an EOR, or EXOR gate) – pronounced as Exclusive OR gate – is a digital logic gate that gives a true (i.e. a HIGH or 1) output when the number of true inputs is odd. This gate is called XOR or exclusive OR gate because its output is only 1 when its input is exclusively 1.

## What is the truth table for XOR gate?

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 gates inputs are low (0), or if both of its inputs are high (1), then the output of the XOR gate is low.

## What is the point of truth tables?

A truth table is a logically-based mathematical table that illustrates the possible outcomes of a scenario. The truth table contains the truth values that would occur under the premises of a given scenario. As a result, the table helps visualize whether an argument is logical (true) in the scenario.
