Logic Gates are defined as digital circuits that operates on one or more digital inputs and produces an one output signal. Logic gates are called digital circuits because the input and output signals are either lower voltage(0) or high voltage(1).
These are also called logic circuits because they can be easily analysed by Boolean algebra.
Logic Gates can be divided into two types:

Basic gates are defined as gates very basic and are not complicated. These are of three types
Daraind Gates are those gets which are made of combination of basic Gates. These are of four types:
Let us discuss all the gates one by one.
The AND gate is a logic circuit which has two or more inputs and one single output. The AND Gate will produce output 1 only when both the inputs are 1. If there is any 0 in the input the output will be 0.
Logic Symbol for AND gate is given below:
Truth Table for XNOR Gate
| Input | Input | Output |
| A | B | Y |
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
