Signal Processing is a field of applied mathematics and Engineering, it deals in analysing signals in both discreet and continuous time. Whereas Digital Signal Processing is concerned with analyzing discrete time signals by a sequence of numbers or symbols. The DSP aims at measuring, filtering and compressing the analog signals. The signal processing is divided under various sub heads, such as: Analog Signal Processing : It is for signals that have not been digitized , it involves both linear electronic circuits and non linear circuits. Discrete Time Signal Processing : It is for sampled signals that are considered definite at discrete time intervals, and can only be quantized in time and not magnitude. Digital Signal Processing : It involves processing of digitized discrete time signals. A continuously changing wave form is converted into a series of different levels.
