This text contains a comprehensive discussion on continuous and discrete time signals and systems with many MATLAB® examples. It is written for junior and senior electrical 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 at San Jose State University, San Jose, California, 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 MathWorks™ Inc., 3 Apple Hill Drive , Natick, MA 01760-2098

The elementary signals are reviewed in Chapter 1 and several examples are presented. The intent 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 discusses the state
variable method, and Chapter 6 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 contains a review of complex numbers, and Appendix C discusses matrices.
New to the Second Edition
This is an refined revision of the first edition. The most notable changes are chapter-end summaries,
and detailed solutions to all exercises. The latter is in response to many students and working
professionals who expressed a desire to obtain the author’s solutions for comparison with their own.
The author has prepared more exercises and they are available with their solutions to those
instructors who adopt this text for their class.
The chapter-end summaries will undoubtedly be a valuable aid to instructors for the preparation of presentation material. The last major change is the improvement of the plots generated by the latest revisions of the MATLAB® Student Version, Release 13.
