Digital Signal and Image Processing using MATLAB, Volume 1: Fundamentals, 2nd Edition

Foreword

Simulation is an essential tool in any field related to engineering techniques, whether it is used for teaching purposes or in research and development.

When teaching technical subjects, lab works play an important role, as important as exercise sessions in helping students assimilate theory. The recent introduction of simulation tools has created a new way to work, halfway between exercise sessions and lab works. This is particularly the case for digital signal processing, for which the use of the MATLAB^® language, or its clones, has become inevitable. Easy to learn and to use, it makes it possible to quickly illustrate a concept after introducing it in a course.

As for research and development, obtaining and displaying results often means using simulation programs based on a precise “experimental protocol”, as it would be done for actual experiments in chemistry or physics.

These characteristics have led us, in a first step, to try to build a set of exercises with solutions relying for the most part on simulation; we then attempted to design an introductory course on Digital Signal and Image Processing (DSIP) mostly based on such exercises. Although this solution cannot replace the traditional combination of lectures and lab works, we do wonder if it isn’t just as effective when associated with exercise sessions and a few lectures. There is of course no end in sight to the debate on educational methods, and the amount of experiments being conducted in universities and ...
