Digital Signal Processing

This an alternate cover for 0132146355 / 9780132146357Here is an up-to-date and detailed introduction to the fundamentals of processing signals by digital techniques and their applications to practical problems.Coverage includes discrete-time signals and systems, z-transform, discrete Fourier transforms, flow graph and matrix representations of digital filters, digital filter design, the fast Fourier transform, discrete Hilbert transforms, discrete random signals, effects of finite register length, homomorphic signal processing, and power spectrum estimation.Among the features:· Introduces concepts of two-dimensional signal processing.· Presents newly published material based on the authors' original research.· Includes thorough treatment of Tellegen's theorem, other digital network theorems, fast Fourier transform algorithms, and homomorphic processing.· Provides more than 200 carefully prepared illustrative problems-all closely integrated with the text.
