1. Introduction

Logic gates are the basic building blocks of any digital system. They are electronic circuits having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic.

2. Basic Gates

AND Gate

Output is HIGH (1) only if all inputs are HIGH.

Y = A . B

OR Gate

Output is HIGH (1) if at least one input is HIGH.

Y = A + B

NOT Gate

Inverts the input. HIGH becomes LOW and vice versa.

Y = A'

3. Universal Gates

NAND and NOR gates are called universal gates because they can be used to implement any other logic function.

NAND Gate

Complement of AND gate.

Y = (A . B)'

NOR Gate

Complement of OR gate.

Y = (A + B)'
