Digital Signal Processing [Paperback] [Jan 01, 1988] OPPENHEIM & SCHAFER by and-ronald-w-schafer-alan-v-oppenheim

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, dis-crete random signals, effects of finite register length, homo-morphic signal processing, and power spectrum estimation.the authors closely integrate over 200 carefully prepared homework problems, many of which extend the funda-mentals and direct the student towards practical application.the text is ideal for courses in digital signal processing at the senior or first year graduate level courses. The book assumes a background of advanced calculus, including an introduction to complex variable theory and an exposure to linear system theory for continuous line signals, including laplace and fourier transforms
