Preface: Why and How this Book was Written

Sometimes it is easier to say what a book is not than what it exactly represents. It may be also better to resume the authors' motivations than to explain the book content itself.

From this point of view, our book is certainly not a traditional course, although it recalls many theoretical signal processing concepts. Indeed, we emphasize a limited number of important ideas instead of making a detailed description of the involved concepts. Intuitive manners have been used to link these concepts to physical aspects. Hence, we hope that reading this book will be much more exciting than studying a traditional signal processing course.

This book is also not a physics course, although a major purpose of most proposed exercises is to link abstract signal processing concepts to real-life problems. These connections are illustrated in a simple and comprehensive manner through MATLAB® simulations.

The main topics of this book cover the usual program of an undergraduate signal processing course. It is especially written for language and computer science students, but also for a much larger scientific community who may wish to have a comprehensive signal processing overview. Students will certainly find here what they are looking for, while others will probably find new and interesting knowledge.

This book is also intended to illustrate our pedagogical approach, which is based on three major reasons:

1. Students need to know how the teaching provided ...
