The second, strongly enlarged edition of the textbook gives a
substantial 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. The author devotes important parts 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. The author has substantially updated all
chapters and added some important topics like Allpass filters. With an
emphasize put on the practical implementation of theoretical concepts,
the book is a reference for advanced students as well as practicing
engineers.
