Description: It provides an overview of DSP. It starts with a classification of the types of signals encountered in DSP. It then introduces in a heuristic way the characterization of signals in terms of frequency spectrums. The filtering process as a means of transforming or altering the spectrum of a signal is then described. The second half of the chapter provides a historical perspective of the evolution of analog and digital filters and their applications. The chapter concludes with two specific applications that illustrate the scope, diversity, and usefulness of DSP. Platform: |
