Digital signal processing is ubiquitous. It is an essential ingredient in many of today's electronic devices, ranging from medical equipment to weapon systems. It makes the difference between dumb and intelligent systems. This book is organized into five parts: (1) Introduction, which contains an account of Prof. Constantinides' contribution to the field and brief summaries of the remaining chapters of this festschrift, (2) Digital Filters and Transforms, which covers efficient digital filtering techniques for improving signal quality, (3) Signal Processing, which provides an insight into fundamental theories, (4) Communications, which deals with some important applications of signal processing techniques, and (5) Finale, which contains a discussion on the impact of digital signal processing on our society and the closing remarks on this festschrift.

"This book is a very valuable addition to the signal processing literature. All chapters are written by internationally acclaimed researchers in the field addressing hot topics of current interest. Most of these renowned experts carry the technical DNA inherited from Prof. Constantinides, a living proof of how outstanding genetic information can lead to fruitful contributions to society development.The book includes eighteen survey chapters on the general areas of digital filters and transforms, signal processing, and communications, beautifully written by the technical heirs of Prof. Constantinides and his contemporary colleagues. Indeed this book reflects some of the many advances that Prof. Constantinides and his generation brought about to the ubiquitous DSP technology that benefits the current generation."- Prof. Paulo S. R. Diniz, Federal University of Rio de Janeiro, Brazil "A fitting tribute to a world-renowned pioneer in digital filter design, DSP, and communications, this book offers panoramic views of the past, present, and future of the theory and applications of these fields. The continual evolutions in time-interleaved A/D converters, all-pass filters, and multi-rate filters have pushed the envelopes of their applications, ranging from wireless communications to human face recognition and seismic signal processing. Authored by leading researchers in these fields, this book provides valuable insights into what have been made possible and potential future developments." - Prof. Yih-Fang Huang. University of Notre Dame, USA "Professor Constantinides has made worldwide impact on DSP through his novel contributions to this area. With his unique energy, he has successfully pushed forward DSP scientists in the fields of education, research, and services. His personal inspiration to attract young scientists to work on DSP, especially in Europe, already started in the 70s with the establishment of the European Association for Signal Processing and the European Journal for Signal Processing as well as the organization of the first international series of meetings on DSP." - Prof. Tapio Saramäki, Tampere University of Technology, Finland "This festschrift covers a number of most recent and important DSP research works, including DSP theories, filter designs, and applications, and is very valuable for the DSP community." - Prof. Soo-Chang Pei, National Taiwan University, Taiwan
