Overview of DSP Signals Signals play an important role in our daily life A signal is a function of independent variables independent variables such as time, distance, position, temperature, and pressure A signal carries information The objective of signal processing is to extract extract the useful information carried by the signal 4 1. Overview of DSP Method information extraction: Depends on the type of signal type of signal and the nature of the nature of the information being carried by the signal DSP is concerned with the mathematical mathematical representation of the signal and the algorithmic algorithmic operation carried out on it 5 1. Overview of DSP Signals can be represented in the domain of the domain of the original original independent variables or in a transformed domain Likewise, the information extraction process may be carried out in the original domain of the signal or in a transformed domain 6 1.
