How do you make a 2 bit magnitude comparator?

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.
