Executive Summary

During the last few decades the field of Digital Signal Processing (DSP) has grown to important both theoretically and technologically. For example, DSP has obtained wide applications in several engineering areas from communication, biomedical, and control to meteorology. In DSP, there are two important types of Systems. The first type of systems performs signal filtering in time domain and hence it is known as Digital filters. The second type of systems provide signal representation frequency domain and are known as Spectrum Analyzer. Digital filtering is one of the most important and powerful tool of DSP. Digital filters are capable of performance specifications that would, at best, be extremely difficult, if not impossible, to achieve with an analog implementation.
