60571-7 Multirate signal processing has recently witnessed a great deal of activity, with a wide range of applications in signal coding and compression, in image processing, multiresolution and wavelet analysis. Multirate Systems and Filter Banks is a completely up-to-date and in-depth treatment of the fundamentals as well as recent advancements in this field. This is a self-contained text providing both theoretical developments and design tools. The book will form a basis for graduate courses in multitrate signal processing. Its encyclopedic nature also makes it a unique reference for researchers. The design methods and examples provide a valuable source of information for the practicing professional.Contents: *Review of discrete-time systems and digital filters *Multirate signal processing fundamentals *Multirate filter banks and perfect reconstruction systems *Paraunitary filter banks *Extended lapped orthogonal transforms *Roundoff noise analysis *Wavelet transforms and relation to multirate filter banks *Multidimensional multirate systems *Review of multi-input multi-output systems *Detailed study of paraunitary systems *Five appendices on topics such as subband quantization, transform coding, spectral factorization, matrix theory, and random processes. The text contains over 400 illustrations. There are many well-chosen examples and design-examples, and over 300 problems to be solved.
