Which logic gate is a equality comparator?

exclusive NOR gate
The circuit of the equality comparator consists of an exclusive NOR gate (XNOR) per pair of input bits. If the two inputs are identical (both 1s or both 0s) an output of logic 1 is obtained.

What is a 4-bit comparator IC?

The 4-bit comparator is mostly available in IC form and common type of this IC is 7485. This IC can be used to compare two 4-bit binary words by grounding I (A>B), I (A

What is an equality comparator?

An equality comparator is a hardware electronic circuit made from logic gates that takes two binary numbers as input determines whether these are equal or not.

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.

Which logic gate performs the comparator function?

A exclusive−OR gate can be used as a basic comparator. Digital comparators are also called as binary or logic comparators. Comparator is a very useful combinational circuit capable of comparing two numbers as input in binary form and determines whether one number is greater than, less than or equal to other number.

What is a 4 bit comparator?

How does a 4-bit comparator work?

Is a comparator a logic gate?

Binary comparators are logic gates circuit used to compare two binary inputs. There are two types of binary comparators: Equality Comparators are used to check if the two binary inputs (A and B) are equal or not.

How is comparator calculated?

Inverting comparator. Remember the equation Av = -Rf/R1. The equation for voltage gain in the inverting mode is Av = -Rf/R1. Since there is no feedback resistor, the gain will be close to infinity and the output voltage will be as negative as possible ie; V-.

How to design a 4-bit comparator?

How to design 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.

An equality comparator is a hardware electronic circuit made from logic gates that takes two binary numbers as input determines whether these are equal or not.

What is a comparator circuit?

A Comparator is a combinational circuit that gives output in terms of A>B, A

How to design a multi-bit equality comparator using XNOR?

Two binary inputs are equal if all their bits are equal. We can therefore design a multi-bit equality comparator by combining several XNOR gates together to compare each bit of both inputs. You can recreate this circuit online using the logic.ly circuit simulator.
