Signal processing is the processing, amplification & interpretation of signals. Signals will are from either various sources. There are various kind of signal processing, based on the nature and severity of the signal, when in the as a result examples.

Digital signal processing - for signals that have been digitized. Processing is handle digital circuits, microprocessors or computers. Analog signal processing - for signals that have non been digitized Audio signal processing - for electrical signals representing sound Speech signal processing - for interpreting spoken words Video signal processing - for interpreting moving pictures Array processing
