What is xnor

Trusted by Teachers I just wanted to thank you for creating the Logicly gate simulation. Michael Gamson, Hillel School of Tampa. Enjoyed by Students I'd just like to thank you for making Logicly. Andrew Sum. The truth table for an XNOR gate with two inputs appears to the right.

However, if either input differs from the other, the gate will output a 0. Logic gates such as XNOR can be used in cutting edge microprocessors, containing upwards of over million gates.

In other forms, logic gates are integrated into nearly every modern piece of technology. For example, a hallway that has two light switches. It is a hybrid gate. The output level of the XNOR gate is high only when both of its inputs are the same, either 0 or 1. It is a simple form of the hybrid gate XNOR.

In this type of XNOR gate, there are only two input values and an output value. The output level is high when both inputs are set to high 1. The Boolean expression of the logical Ex-OR gate is as follows:. The main disadvantage of this implementation is that we use different types of gates to form a single XNOR gate.

This is an easier way of producing Ex-NOR gate functionality. Ex-NOR gates are used mainly in electronic circuits that perform arithmetic operations and data checking such as Adders , Subtractors or Parity Checkers , etc. As the Ex-NOR gate gives an output of logic level "1," whenever its two inputs are equal, it can be used to compare the magnitude of two binary digits or numbers and so Ex-NOR gates are used in Digital Comparator circuits.
