## How does a digital comparator work?

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.

### What is 3bit 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. 3-bit magnitude. The equal functions are A0 = B0, A1= B1, A2 = B2.

How many types of digital comparators are?

two
There are two main types of digital comparators available: Identity comparator and Magnitude comparator.

What is 2-bit digital comparator?

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 a 4 bit comparator?

4-Bit Magnitude Comparator – A comparator used to compare two binary numbers each of four bits is called a 4-bit magnitude comparator. It consists of eight inputs each for two four bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers.

### How does an 8-bit comparator work?

With 8-bit numbers, the comparator compares each bit of the number with an XNOR gate. Two 8-bit numbers are only equal if each bit is identical. Inputs: The bits of two numbers which need to be compared (A, B), 8 bits for each number. If the two inputs are equal (both logic 1 or both logic 0) then a logic 1 is output.

What is a 4-bit comparator?

How many inputs are required for a 3 bit digital comparator?

How many inputs are required for a digital 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. Thus, there are two inputs required for a digital comparator (i.e. A & B).
