Signal Processing is divided into two categories: analog signal processing and digital signal processing. This study focuses on the digital signal processing. A signal is a one-dimensional function. A digital signal processing is an area of science and engineering that has developed rapidly over the
past 30 years . The meaning of these terms (Digital, Signal, Processing) are listed below:
Signal : A parameter (an electrical quantity or an eeffect) that can be varied in such a way as to convey information.
Digital : Operating by the use of discrete signals to represent data in
the form of numbers.
Processing : A series of operations performed according to programmed
These definitions can be combined in one definition called Digital Signal Processing (DSP).
Digital Signal Processing : Changing or analyzing information which is measured as discrete sequences of numbers.
