Example:
Imagine you're trying to communicate with a friend across a noisy room by using a flashlight to signal a series of on and off blinks that represent a secret code you both know. This is similar to how digital signals work, where electrical pulses switch on and off to convey information using binary numbers. Just as each blink of your flashlight represents a piece of the message, each electrical pulse in a digital signal represents a binary digit (either 0 or 1), allowing complex information to be communicated clearly despite potential noise.

Digital Signal: A series of electrical pulses that represents the digits of binary numbers. Digital signal. A digital signal is a type of signal that uses binary numbers 0s and 1s to represent information.
