A very common method of digital operation is achieved by using current pulses.
Integrated circuits containing many transistors are most commonly used as switching devices in digital electronics logic gates.
The three basic types of digital logic gates are the AND gate, the OR gate, and the NOT gate.
An important function of NOT gate is to produce signal inversion or an input signal that is opposite in nature to the output signal.
