The study and implementation of microphone arrays originated over 20 years ago. Thanks to the research and experimental developments pursued to the present day, the field has matured to the point that array-based technology now has immediate applicability to a number of current systems and a vast potential for the improvement of existing products and the creation of future devices. In putting this book together, our goal was to provide, for the first time, a single complete reference on microphone arrays. We invited the top re searchers in the field to contribute articles addressing their...

Hybrid systems research focuses on modelling, design and validation of interacting systems (plants) and computer programs (control automata). This volume is devoted to the following topics: hybrid systems models; formal verification; computer simulation; goal reachability; algorithms for extracting hybrid control programs; and application models for avionics, highway traffic control and air traffic control.

Multidimensional or spatio-temporal signals are important in image processing and television. This book presents the mathematical methods for processing multidimensional signals. It describes applications in system analysis, measurement and optimization and signal restoration, with varying examples of applications.

For many decades, hybrid devices have been used to connect 2-wire local circuits and 4-wire long distance circuits in telephone lines. This leads to a weIl known problem, whereby echoes are generated. The delay introduced by telecommunication satellites exacerbated this problem and the need for new methods of echo control soon became obvious. The best solution to date for solving this problem was invented in the 1960s at Bell Labs by Kelly, Logan, and Sondhi, and consists of identifying the echo path generated by the hybrid by means of an adaptive filter, a technique that became known as an...

The most outstanding feature of this book is that it treats the design of filters that approximate a constant group delay, and both, the prescribed magnitude and group delay response of one-dimensional as well as two-dimensional digital filters. It so fills a void in the literature, that almost solely deals with the magnitude response of the filter transfer function. The volume contains many of the important results that have appeared in professional journals only recently.

Reporting the state of the art of color image processing, this monograph fills an existing gap in the literature on digital signal and image processing. It can serve the needs of different users at different levels: as a textbook which covers a graduate image processing course, as a up-to-date reference for researchers since it offers a broad survey of the relevant literature, and as a relevant information source for development engineers who work in the design and the implementation of various image processing tasks. Part of the material in the book was the basis of seminars at the...

There are more than 100 books on Circuit Analysis, Network Synthesis, Ana log and Digital Filters and Signal Processing written at the undergraduate and graduate level and a few more written as Reference and Handbooks. When and if they discuss the design of analog and digital filters, they treat mainly the approximation of the magnitude response of the filters and very little of their phase or group delay response. There is hardly any discussion of designing fil ters that simultaneously approximate the magnitude and group delay response of the filters. Thus most of the books routinely discuss...
