Digital Filters: Basics and Design

It is the aim of this textbook to give insight into the characteristics and the design of digital filters. It briefly introduces to the theory of continuous-time systems and the design methods for analog filters. Time-discrete systems, the basic structures of digital filters, sampling theorem, and the design of IIR filters are widely discussed. Important parts of the book are devoted to the design of non-recursive filters and the effects of finite register length. The explanation of techniques like oversampling and noise shaping conclude the book. It is completed by an annex containing a selection of tables of filter parameters for Butterworth, Chbeyshev, Cauer, and Bessel filters. Furthermore, several computer routines for filter design programs are given.
