What is Analog Signal Processing?
Analog signal processing is the mathematical operation or analysis of analog signals through analog means. This can be conducted in either a discrete or continuous time frame and represents the main way in which these operations perform. Usually this processing involves some form of control, filtering, deblurring or denoising. In order for the signal to be analog, it must have a continuous value. Basically, the signal must feature a time varying flow of information. Each fluctuation in the signal has important meaning, unlike digital, which deals with numeric representation. The most common context of analog is in electronics, when a signal is sent as physical information.
