Digital Signal Processing

the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing.

 What is Digital Signal Processing?
      Digital Signal Processing is concerned with the representation of signals by a sequence of numbers or symbols and the processing of these sequences.

What is a Signal?
    A function that conveys information generally about the state or behavior of a system.
    Mathematically, Signals are represented as a function of one or more independent variables.
What is Signal Processing?
    It involves analyzing, modifying, and synthesizing signals to pull meaning out of it.
