This textbook provides comprehensive coverage for courses in the basics of design and implementation of digital filters. The book assumes only basic knowledge in digital signal processing and covers state-of-the-art methods for digital filter design and provides a simple route for the readers to design their own filters. The advanced mathematics that is required for the filter design is minimized by providing an extensive MATLAB toolbox with over 300 files. The book presents over 200 design examples with MATLAB code and over 300 problems to be solved by the reader. The students can design and modify the code for their use. The book and the design examples cover almost all known design methods of frequency-selective digital filters as well as some of the authors' own, unique techniques. Discusses in detail state-of-the-art methods for advanced digital filter design; Provides an extensive MATLAB for digital filter design which provides a simple route for the readers to design their own filters; Covers design of FIR filters, wave digital filters, frequency-response masking filters, sample rate converters, multirate filters, and hardware implementation techniques.
