analog circuit
Non-digital signal path
An analog circuit processes continuous electrical signals—voltages or currents that vary smoothly rather than switching between discrete states.
Unlike digital circuits that work in ones and zeros, analog circuits handle the full range of values in between: The amplifier's analog circuitry faithfully reproduces the original sound wave.
Audio equipment, radio receivers, and sensors typically rely on analog circuits to capture or reproduce real-world phenomena.
