## What is the Boolean expression for a XOR gate?

XOR gate. The exclusive OR gate works the same as an OR gate, but will output 1 only if one or the other (not both) inputs are 1. The XOR gate is indicated with the extra curved line to the left of the main shape. The Boolean expression is written as Q = A XOR B.

## What is the Boolean expression for a 3 input XOR gate?

y = a’bc’ + ab’c’ + ab’c The combinational circuit constructed from these two equations is shown in (a) of Figure 1.4(f). . Each 3-variable AND term is replaced by a 3-input AND gate.

**What is XOR gate discuss the role of XOR gate in parity generator?**

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. The output of the XOR function, which is 1 if the number of 1’s is odd and 0 if the number of 1’s is even, is referred to as a ‘parity’ bit.

**How many gates are used in the implementation of the XOR gate?**

An XOR gate circuit can be made from four NAND gates.

### What is an example of a Boolean expression?

A Boolean expression is any expression that has a Boolean value. For example, the comparisons 3 < 5, x < 5, x < y and Age < 16 are Boolean expressions. The comparison 3 < 5 will always give the result true, because 3 is always less than 5.

### How do you write Boolean expressions?

How to insert a Boolean algebra equation

- Create your own equation.
- Under Equation Tools, on the Design tab, in the Structures group, click the Accent button:
- In the box:
- 3.1. Enter A.
- 3.2.
- 3.3.
- Then enter =.
- Under Equation Tools, on the Design tab, in the Structures group, click the Accent button and then choose Bar.

**How to make XOR gate from NAND?**

The top and bottom NAND would take place of an AND, the bottom two on the left are invertors. and the output NAND takes place of an output OR, this would have an equivalent of using 5 gates of different types. 5 NAND gates are required to realize an XNOR gate.

**What is a XOR gate?**

XOR Gate with Truth Table and simulation. The project contains the 2 types of circuit. One is the simle XOR gate through its IC in Proteus. The 2nd is the proper arrangemnt of basic gates through which we can get the same output.These are simple

## How does a XOR gate work?

– // C/C++ – if ( 1 == 1 ) – // when if () is true – if ( (1 XOR 1) == 0) – // when result of XOR is 0 -> equal values

## What is equation for 3 input XOR gate?

The Boolean function for the 3- input XOR gate is: Q = A ⊕ B ⊕ C = A B C + A B C + A B C + A B C . The truth table and logic symbol for 3-input XOR gate is given below. 3-Input Ex-OR Gate Logic Symbol. Truth Table of 3 Input XOR Gate. For 3-input XOR gates, we can have the HIGH input when odd numbers of inputs are at HIGH level.
