An Analog Signal Processor (ASP) is a device that manipulates continuous signals to perform various functions, such as filtering, amplification, and modulation. Unlike digital signal processors, which work with discrete data, ASPs handle real-time analog signals, making them suitable for applications like audio processing and telecommunications. ASPs are commonly used in devices like radios, televisions, and audio equipment to enhance sound quality and improve signal clarity. They can also be found in medical devices for processing signals from sensors, ensuring accurate readings and effective monitoring of patient health.
