"Discrete linear systems and digital signal processing have been treated for years in separate publications. ElAli has skillfully combined these two subjects into a single and very useful volume. ... Useful for electrical and computer engineering students and working professionals... a nice addition to the shelves of academic and public libraries.


"Summing Up: Highly Recommended."

- S.T. Karris, University of California, Berkeley in CHOICE


Typically, books on linear systems combine coverage of both discrete and continuous systems all in a single volume. The result is usually a daunting mountain of information that fails to sufficiently explain either subject. With this in mind, Discrete Systems and Digital Signal Processing with MATLAB (R), Second Edition responds to the need in engineering for a text that provides complete, focused coverage of discrete linear systems and associated problem solution methods.


With its simplified presentation, this book follows a logical development that builds on basic mathematical principles to cover both discrete linear systems and signal processing. The author covers all traditional topics and includes numerous examples that are solved analytically and, when applicable, numerically using the latest version of MATLAB (R). In addition to the classical coverage, the author includes complete and stand-alone chapters on IIR and FIR filter design, block diagrams, state-space, and sampling and transformations, as well as a unique chapter on FFT and its many applications. The book also introduces many examples using the MATLAB data acquisition toolbox in different chapters.


Ideal either as a textbook for the required course in the electrical and computer engineering curriculum or as an updated refresher for seasoned engineers, this resource offers a wealth of examples, exercises, problems, and author insights.

Taan S. ElAli, Ph.D, has been a full professor of electrical engineering since 2002. Earning the rare honor of senior membership in the IEEE, he has worked full time for about 17 years at several academic institutions nationally and internationally in the areas of curriculum development, accreditation, teaching, research, and leadership. A former Fulbright scholar, Dr. ElAli obtained his BS in electrical engineering in 1987 from The Ohio State University, Columbus, United States, and his MS in systems engineering in 1989 from Wright State University, Dayton, Ohio, United States. He earned another MS in applied mathematics and a Ph.D in electrical engineering-with a specialization in systems, controls, and signal processing-from the University of Dayton in 1991 and 1993, respectively. Among his many awards and accomplishments, Dr. ElAli has discovered a new approach to dynamic system identification. His extensive research and interest in revolutionizing the engineering education has led to the publishing of his Innovations in Engineering Education book.
