Opis

This excellent text is designed to be an easy-to-read, practical guide for practitioners and researchers requiring an accessible reference text on digital signal processing. The book is split into six self-contained chapters, allowing the reader to quickly locate and implement different aspects of the subject as required. The authors primarily introduce the concept of signal processing, providing information on types of signals, transformations (for example, the Z-transform), parametric and nonparametric characterizations, and analog to digital conversions. Next, they present the fundamental concepts needed for understanding systems using signal processing, like linearity, stability, stability, convolution, and linear system representations in time and frequency domains. There is also a description of the concept of noise and its significance in such systems.

Blurb

Digital signal processing is essential for improving the accuracy and reliability of a range of engineering systems, including communications, networking, and audio and video applications. Using a combination of programming and mathematical techniques, it clarifies, or standardizes the levels or states of a signal, in order to meet the demands of designing high performance digital hardware.

Written by authors with a wealth of practical experience working with digital signal processing, this text is an excellent step–by–step guide for practitioners and researchers needing to understand and quickly implement the technology. Split into six, self–contained chapters, Digital Signal Processing: A Practitioner s Approach covers:

• basic principles of signal processing such as linearity, stability, convolution, time and frequency domains, and noise;
• descriptions of digital filters and their realization, including fixed point implementation, pipelining, and field programmable gate array (FGPA) implementation;
• Fourier transforms, especially discrete (DFT), and fast Fourier transforms (FFT);
• case studies demonstrating difference equations, direction of arrival (DoA), and electronic rotating elements, and MATLAB programs to accompany each chapter.

A valuable reference for engineers developing digital signal processing applications, this book is also a useful resource for electrical and computer engineering graduates taking courses in signal processing.
