Analog signal processing involves the manipulation of continuous signals to enhance or modify their characteristics. This type of processing is commonly used in various applications, such as audio and video systems, where signals vary smoothly over time. Techniques include filtering, amplification, and modulation, which help improve signal quality and transmission. In analog signal processing, devices like amplifiers and filters play crucial roles. These components can adjust the strength of a signal or remove unwanted noise, ensuring that the output is clearer and more accurate. Unlike digital signal processing, which deals with discrete values, analog processing maintains the natural flow of the signal.
