## How many inputs will a 3 bit comparator have?

Table of Contents

There are 3 inputs A, B, C which will also return in the form of 3 outputs.

What is magnitude comparator explain?

A digital comparator or magnitude comparator is a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number. Comparators are used in central processing units (CPUs) and microcontrollers (MCUs).

How many inputs and outputs are there in comparator?

Explanation: A comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. In a digital comparator, only 3 outputs are possible (i.e. A = B, A >B, A < B). Other than this, the output will be 0.

### What is 2-bit magnitude comparator?

A comparator used to compare two binary numbers each of two bits is called a 2-bit magnitude comparator. It consists of four inputs and three outputs to generate less than, equal to and greater than between two binary numbers.

What is magnitude comparator design a 3 bit magnitude comparator?

A comparator that compares two binary numbers (each number having 3 bits) and produces three outputs based on the relative magnitudes of given binary bits is called a 3-bit magnitude comparator.

How does a 2 bit comparator work?

A 2-bit comparator compares two binary numbers, each of two bits and produces their relation such as one number is equal or greater than or less than the other. The figure below shows the block diagram of a two-bit comparator which has four inputs and three outputs.

## What is 2-bit comparator?

How many bits do these comparators work on?

A comparator receives two N-bit binary numbers A and B and outputs a 1-bit comparison result.

What is an 8-bit comparator?

An 8-bit comparator compares the two 8-bit numbers by cascading of two 4-bit comparators. The circuit connection of this comparator is shown below in which the lower order comparator AB outputs are connected to the respective cascade inputs of the higher order comparator.

### How can a 2 bit comparator make a 4-bit comparator?

Firstly lower two bits of A & B are compared and then next bits and then next. We feed the result of first 2 bits to lower bit of next comparator. Then we feed the result of this comparator to lower bit of next comparator. This way with the use of 3 2-bit comparators we get 4-bit comparator.
