Preface

This text contains a comprehensive discussion on continuous and discrete time signals and

systems with many MATLAB® and several Simulink® examples. It is written for junior and

senior electrical and computer engineering students, and for self − study by working professionals.

The prerequisites are a basic course in differential and integral calculus, and basic electric circuit

theory.

This book can be used in a two − quarter, or one semester course. This author has taught the

subject material for many years and was able to cover all material in 16 weeks, with 2½ lecture

hours per week.

To get the most out of this text, it is highly recommended that Appendix A is thoroughly

reviewed. This appendix serves as an introduction to MATLAB, and is intended for those who

are not familiar with it. The Student Edition of MATLAB is an inexpensive, and yet a very

powerful software package; it can be found in many college bookstores, or can be obtained directly

from

The elementary signals are reviewed in Chapter 1, and several examples are given. The purpose of

this chapter is to enable the reader to express any waveform in terms of the unit step function, and

subsequently the derivation of the Laplace transform of it. Chapters 2 through 4 are devoted to

Laplace transformation and circuit analysis using this transform. Chapter 5 is an introduction to

state − space and contains many illustrative examples. Chapter 6 discusses the impulse response.

Chapters 7 and 8 are devoted to Fourier series and transform respectively. Chapter 9 introduces

discrete − time signals and the Z transform. Considerable time was spent on Chapter 10 to present

the Discrete Fourier transform and FFT with the simplest possible explanations. Chapter 11

contains a thorough discussion to analog and digital filters analysis and design procedures. As

mentioned above, Appendix A is an introduction to MATLAB. Appendix B is an introduction to

Simulink, Appendix C contains a review of complex numbers, and Appendix D is an introduction

to matrix theory.

New to the Second Edition

This is an extensive revision of the first edition. The most notable change is the inclusion of the

solutions to all exercises at the end of each chapter. It is in response to many readers who

expressed a desire to obtain the solutions in order to check their solutions to those of the author

and thereby enhancing their knowledge. Another reason is that this text is written also for self −
