Analog signal
An analog or analogue is any variable signal continuous in both time and amplitude. It differs from a
digital signal in that small fluctuations in the signal are meaningful. Analog is usually thought of in an
electrical context, however mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.
