Which of the following Gates is known as equality comparator?

Which of the following Gates is known as equality comparator?

4-bit Equality Comparator 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.

Which logic gate is known as Equality gate?

Explanation: A 2 Input XNOR gate is called as equality detector. They are called so because, when the two inputs of the XOR gate is different its output is Logic Zero(LOW), but when both the inputs are same then the output is Logic one (HIGH).

Which logic gate acts as a comparator?

A logic comparator is made by two AND gates, Two inverter/NOT gates, and one NOR gate to be. It takes two inputs and compare the two inputs and produce an output, based on the condition or values of the two inputs. Two common types of digital comparators exist, an Identity.

What is equivalence logic gate?

In other words, an even number of logic “1’s” on its inputs gives a logic “1” at the output, otherwise is at logic level “0”. Then this type of gate gives and output “1” when its inputs are “logically equal” or “equivalent” to each other, which is why an Exclusive-NOR gate is sometimes called an Equivalence Gate.

Which gate is inequality detector?

XOR gate
This is the reason an XOR gate is also called an anti-coincidence gate or inequality detector. This gate is called XOR or exclusive OR gate because its output is only 1 when its input is exclusively 1.

What are the logic conditions in comparator?

A comparator compares two or more inputs using one, or a number of different comparisons. when the given relationship(s) is true, an output signal is given (logic 0 or logic 1). Comparators are only modeled using the if statement with an else clause and no else – if clauses.

Which gate is also called any OR all gate?

Go to page. AND gate is called an all or nothing gate. Because it produce high only when all its inputs are high.

Which gate can be used for equality checking *?

The Exclusive-OR (XOR) and Exclusive-NOR (XNOR) are very useful gates often used in equality detectors and parity generator circuits.

Why is an Exclusive NOR gate also called as equality gate?

Why is an exclusive-NOR gate also called an equality gate? The output is false if the inputs are equal. The output is true if the inputs are opposite. Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function.

Which logic gates are known as universal gate and why?

NAND and NOR gates are called universal gates because they perform all the Logic functions OR, AND and NOT.

How many equal conditions are there in 4-bit 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.

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.

Which logic gate is combination of and and NOT gate?

This basic logic gate is the combination of AND and NOT gate. This gate is the combination of OR and NOT gate. In XOR gate the output of a two-input XOR gate attains the state 1 if one adds only input attains the state 1. A. B ˉ + A ˉ. B In XNOR gate the output is in state 1 when its both inputs are the same that is, both 0 or both 1.

What is the difference between gate 1 and Gate 2?

Gate 1 produces the function A>B and gate 3 gives A

Why do we use the equations in logic gates?

Because it is possible to achieve the most straightforward equation using them, and remember, the simpler the equation, the lesser the logic gates required. That is the aim of any designing process – to obtain the simplest hardware implementation. A=B = .
