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.
Circuit Diagram
A simple bipolar transistor setup demonstrates the NOT gate’s working principle, where it inverts the input signal.
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.
