Continuous signal

A continuous signal is a type of signal that varies smoothly over time or space, meaning its values change in a steady, uninterrupted way. Unlike signals that are only defined at specific points (discrete signals), continuous signals can take on any value within a range, without jumps or gaps. Examples include the sound of a musical note or the temperature changing throughout the day. These signals are often represented using mathematical functions that provide a value for every moment, making them fundamental for processes like audio transmission, measurements, and control systems.
