Analog Signal Processors are electronic devices that manipulate continuous signals, such as sound, light, or radio waves. They perform various functions like filtering, amplifying, and modulating these signals to improve their quality or extract useful information. Common applications include audio processing in music equipment and telecommunications. These processors work with analog signals, which differ from digital signals that represent data in binary form. By using components like resistors, capacitors, and transistors, Analog Signal Processors can modify signals in real-time, making them essential in industries such as broadcasting and medical imaging.
