Analog Signal Processing refers to the manipulation of continuous signals to improve or modify their characteristics. This process involves various techniques such as filtering, amplification, and modulation, which help in enhancing the quality of the signal for transmission or storage. In analog systems, signals are represented by physical quantities, such as voltage or current, that vary over time. Unlike digital signal processing, which deals with discrete values, analog processing maintains the original waveform, making it suitable for applications like audio and radio communications where fidelity is crucial.
