Описываются эффективные структуры и методы проектирования банков цифровых фильтров. Подробно рассматриваются ДПФ–модулированные и косинусно–модулированые банки фильтров как равнополосные, так и неравнополосные на основе фазовых звеньев. Рассматривается ДПФ с неравномерным частотным разрешением (Warped Discrete–Fourier Transform WDFT), позволяющее аппроксимировать психоакустические шкалы для построения перцептуально мотивированных систем сжатия и передачи речевой информации, а также систем повышения качества речи. Все примеры сопровождаются программной реализацией в среде MATLAB.

The purpose of this book is to bridge the gap between introductory signal processing classes and the mathematics prevalent in contemporary signal processing research and practice, by providing a unified applied treatment of fundamental mathematics, seasoned with demonstrations using MATLAB®. This book is intended not only for current students of signal processing, but also for practicing engineers who must be able to access the signal processing research literature, and for researchers looking for a particular result to apply. It is thus intended both as a textbook and as a reference.

This book provides an easy to understand overview of nonlinear behavior in digital filters, showing how it can be utilized or avoided when operating nonlinear digital filters. It 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.
Hilbert-Huang Transform and its application

The HilbertHuang Transform (HHT) represents a desperate attempt to break the suffocating hold on the field of data analysis by the twin assumptions of linearity and stationarity. Unlike spectrograms, wavelet analysis, or the WignerVille Distribution, HHT is truly a time–frequency analysis, but it does not require an a priori functional basis and, therefore, the convolution computation of frequency. The method provides a magnifying glass to examine the data, and also offers a different view of data from nonlinear processes, with the results no longer shackled by spurious harmonics the artifacts of imposing a linearity property on a nonlinear system or of limiting by the uncertainty principle, and a consequence of Fourier transform pairs in data analysis. This is the first HHT book containing papers covering a wide variety of interests. The chapters are divided into mathematical aspects and applications, with the applications further grouped into geophysics, structural safety and visualization.
Robust control design with MATLAB

Robustness is often of crucial importance in control system design. Real engineering systems are vulnerable to external disturbance and measurement noise and there are always discrepancies between mathematical models used for design and the actual system in practice.
Robust Control Design with MATLAB® helps you learn how to use well–developed advanced robust control design methods in practical cases. To this end, several realistic control design examples ranging from teaching–laboratory experiments, such as a massdamperspring assembly, to complex systems like a flexible link manipulator are given detailed presentation. All the design exercises are conducted using MATLAB® Robust Control Toolbox, Control System Toolbox and Simulink®.

Wavelet and subband transforms have been of great interest in the fields of engineering and applied mathematics. The theories of these powerful signal–processing tools have matured and many applications utilizing them are emerging in different disciplines. This book, comprising eleven chapter contributions from prominent researchers in the field, focuses on communications and multimedia applications of wavelet and subband transforms. The first six chapters of this book deal with a variety of communications applications that significantly benefit from wavelet and subband theories. Similarly, the remaining five chapters present recent advances in multimedia applications of wavelet and subband transforms. These chapters interconnect the requirements of applications with the underlying theory and their engineering solutions.
