A signal is a means of transmitting information. Signals can be classified into analog and digital based on their nature.
Analog Signal:
An analog signal is a continuous signal that varies over time.
It can have an infinite number of values within a given range.
Common examples: Human voice, radio waves, and temperature variations.
Digital Signal:
A digital signal is a discrete signal that represents data using binary (0s and 1s).
It takes only specific values and is not continuous.
Common examples: Computer data, digital audio, and video signals.
