## How do you make a 2 bit magnitude 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.

## Which logic is used in single bit digital comparator?

Exclusive-NOR gates
Digital comparators actually use Exclusive-NOR gates within their design for comparing their respective pairs of bits.

## Which IC used for 2 bit comparator?

This IC can be used to compare two 4-bit binary words by grounding I (A>B), I (AIC7485 comparator.

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

Firstly, a 2-bit comparator is implemented based on the logic expressions from the truth table of each output. Next, likewise, it generates a 4-bit comparator by instantiating two models of the 2-bit comparators and some extra logic gates.

## How many possibilities does two bit number have Mcq?

How many possibilities does two-bit number have? Hint. 18).

## What is a 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. The truth table for a 2-bit comparator is given below:

## What is the truth table for a 4-bit comparator?

The truth table for a 4-bit comparator would have 4^4 = 256 rows. So we will do things a bit differently here. We will compare each bit of the two 4-bit numbers, and based on that comparison and the weight of their positions, we will draft a truth table. Now let’s derive the equations for the three outputs.

## How many rows are in a 4-bit comparator?

The truth table for a 4-bit comparator would have 4^4 = 256 rows. So we will do things a bit differently here. We will compare each bit of the two 4-bit numbers, and based on that comparison and the weight of their positions, we will draft a truth table.

## Which comparator is used to compare two binary numbers?

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