Nonlinear Digital Filters - Analysis and Applications (Electronic book text)

This book provides an easy to understand overview of nonlinear behaviour in digital filters, showing how it can be utilized or avoided when designing nonlinear digital filters. The book gives techniques for analyzing discrete-time systems with discontinuous linearity, enabling the analysis of other nonlinear discrete-time systems, such as sigma delta modulators, digital phase lock loops and turbo coders. In contrast to the traditional approach of analysing digital filters with nonlinearities using statistical analysis, this book is unique in using symbolic dynamics, which allows a more exact analysis. The book has examples and applications of nonlinear filter design and analysis, with Matlab source code provided. It will, therefore, be very useful to professional engineers working with signal processing applications, as well as advanced undergraduates and graduates conducting a nonlinear filter design project. It uses new methods based on symbolic dynamics, enabling the engineer to design more reliable nonlinear digital filters. It includes practical, real-world applications of nonlinear digital filter design.; Many examples, together with Matlab source code are available on an accompanying website.
