What is a NOT Gate?

NOT Gate Definition

A NOT gate, also known as an inverter, is a basic digital logic gate that produces an output which is the opposite of its input.

Symbol and Truth Table

The symbol for a NOT gate reflects its function of inverting the input signal, with a truth table confirming its consistent output inversion.

Working Principle

The NOT gate operates by using a transistor to switch the electrical path based on the input; high input results in low output and vice versa.
