Signals and systems : a MATLAB® integrated approach This book draws on the authors more than 25 years of teaching a course on signals and systems. It provides an interactive visual reinforcement of fundamental concepts like the utility of MATLAB® not just as a computational tool but also as a teaching tool that allows the development of a sophisticated demo program for students to explore while studying the theory of linear systems. It includes a large number of computer modules or applications each linked to a specific example section or figure in the book.
