Digital signal processing : a student guide

Digital signal processing (DSP) systems have developed at a rapid pace over the past two decades, and in recent years they have made a considerable impact in many areas of signal processing applications. DSP techniques play a significant role in the development and effective operation of networked super information highways, and undoubtedly DSP systems will be increasingly applied in response to the ever-growing market demand to provide and rapidly process more and more signal-data transmitted over various forms of communication channel. To promote and sustain such advances, there is a continuing requirement for engineers, scientists and technologists to have a good working knowledge of DSP concepts, design methods and practical implementation considerations. DSP therefore forms a significant part of the core material in many technician, undergraduate and postgraduate courses, especially those offered in electronic and engineering and computing disciplines. This book provides a basic student's guide to DSP and associated practical applications. Throughout, theoretical and practical concepts of DSP are presented in an introductory summary format, underpinned and demonstrated by more than 70 worked examples and a number of case studies. There are also problems at the end of each chapter; solutions to these are provided at the back of the book.
