Features

Treats the subject of transform theory in a unified and integrated way and delineates the interrelations that exist among the various transforms as well as the spectral interrelations between continuous- and discrete-time signals.
Describes practical methods that can be used to design nonrecursive (FIR) and recursive (IIR) digital filters through closed-form as well as iterative methods based on optimization theory.
Provides a summary of the prerequisite knowledge of complex analysis in an appendix.
Treats the effects of finite word length in great detail.
Deals with the Fourier transform in a new practical, yet fairly rigorous, way.
Covers wave digital filters.
Provides a collection of Beamer presentations for key parts of the book which can be downloaded by instructors as well as students - see the top half of page Support Materials.
Provides detailed solutions for the end-of-chapter problems which can be downloaded by instructors, see the bottom half of page Support Materials.
The textbook is supported by the author's DSP software package D-Filter which can be downloaded from page Software.
