Analog signal processing
The English used in this article or section may not be easy for everybody to understand. (February 2012)
An analog signal processor is used to quickly process signals that can be too complex to handle any other way. A comparator is used to offer level triggers correct down to microvolts with reaction times in the picoseconds. Analog filters offer anti-aliasing in sampled value systems as inputs and outputs, and can be used as pre-filters in audio and communications. Analog multipliers and dividers are used to offer brief gain control, radiometric function, or continuous energy measurement, with surprising accuracy. Over-voltage protection applications can protect the front-end of analog transmission/receiver systems, multiplexers. Amplification and filtering for noise removal are the main feature of analog signal processing.
