Truth Table of AND Gate

Symbol of AND Gate

AND Gate in Terms of Transistor

In the given truth table When both inputs A and B are 0, the output is 0.If either input A or B is 0 while the other is 1,the output is 0.Only when both inputs A and B are 1,the output is 1.This behavior reflects the AND gate’s logical operation, where the output is true (1) only when all inputs are true (1).

3 input AND gate

AND Gate

Logic gates are small digital switching circuit that determines the output of two or more inputted functions in Binary format. Logical ‘1’ means ‘True’ or ‘High’ in nature, whereas logical ‘0’ means ‘False’ or ‘Low’ in nature. Based on different logical operations, the output differs. There can be many inputs in a logic gate but there will be only one output. Each logic gate has its own truth table which represents all the combinations of input and output.

What is an AND Gate?

AND gate is the fundamental logic gate that executes the logical multiplication of binary input. The AND operation is carried out in the same way as standard multiplications of 1s and 0s. An AND gate is a logic circuit that performs AND operations on the input of the circuit. When all the inputs are 1, the AND Gate outputs 1, otherwise it outputs 0. A dot (.) denotes the AND operation....
