Digital Filters and Signal Processing

This text presents a general survey of digital signal processing concepts, design methods, and implementation considerations, with an emphasis on digital filters. It is suitable as a textbook for senior undergraduate or first-year graduate courses in digital signal processing. While mathematically rigorous, the book stresses an understanding of digital filters and signal processing systems, with numerous realistic and relevant examples. Hence, practicing engineers and scientists should also find the book a useful reference. This edition contains a substantial amount of new material including, in particular, the addition of MATLAB exercises to deepen the students' understanding of basic DSP principles and increase their proficiency in the application of these principles. Other new features include: normalized frequency utilized in the DTFT, for example, X(ej); new computer generated drawings and MATLAB plots throughout the book; expanded coverage of Types I-IV linear-phase FIR filters; new material on power and doubly-complementary filters; a section on quadrature-mirror filters and their application in filter banks; a section on the design of maximally-flat FIR filters; a section on roundoff-noise reduction using error feedback.
