In this chapter, we introduce the analog filters that are intended to serve as prototypes for the design of corresponding digital filters. Besides describing characteristics of Butterworth, Chebyshev, Cauer and Bessel filters, hints are given as to how the coefficients of these filters are calculated. This will enable the reader to perform calculations going beyond the numerical data given in the design tables in the Appendix.
