Basic Logic Gates

Logic gates are an important concept if you are studying electronics. These are important digital devices that are mainly based on the Boolean function. Logic gates are used to carry out logical operations on single or multiple binary inputs and give one binary output. In simple terms, logic gates are the electronic circuits in a digital system.

In this lesson, we will further look at the different types of basic logic gates with their truth table and understand what each one is designed for.

Types of Basic Logic Gates
There are several basic logic gates used in performing operations in digital systems. The common ones are;
OR Gate
AND Gate
NOT Gate
XOR Gate

OR Gate
In an OR gate, the output of an OR gate attains state 1 if one or more inputs attain state 1.

AND Gate
In the AND gate, the output of an AND gate attains state 1 if and only if all the inputs are in state 1.

NOT Gate
In a NOT gate, the output of a NOT gate attains state 1 if and only if the input does not attain state 1.
