Signals and Systems - Electrical Engineering

Acknowledgments

I would like to acknowledge with gratitude the support and efforts of many people who made the writing of this text

possible. First, to my family—my wife Cathy, my children William, Camila, and Juan, and their own families—many

thanks for their support and encouragement despite being deprived of my attention. To my academic mentor, Professor

Eliahu I. Jury, a deep sense of gratitude for his teachings and for having inculcated in me the love for a scholarly career

and for the theory and practice of signals and systems. Thanks to Professor William Stanchina, chair of the Department

of Electrical and Computer Engineering at the University of Pittsburgh, for his encouragement and support that made

it possible to dedicate time to the project. Sincere thanks to Seda Senay and Mircea Lupus, graduate students in my

department. Their contribution to the painful editing and proofreading of the manuscript, and the generation of the

solution manual (especially from Ms. Senay) are much appreciated. Equally, thanks to the publisher and its editors, in

particular to Joe Hayton and Steve Merken, for their patience, advising, and help with the publishing issues. Thanks

also to Sarah Binns for her help with the final editing of the manuscript. Equally, I would like to thank Professor James

Rowland from the University of Kansas and the following reviewers for providing significant input and changes to

the manuscript: Dimitrie Popescu, Old Dominion University; Hossein Hakim, Worcester Polytechnic Institute; Mark

Budnik, Valparaiso University; Periasamy Rajan, Tennessee Tech University; and Mohamed Zohdy, Oakland University.

Thanks to my colleagues Amro El-Jaroudi and Juan Manfredi for their early comments and suggestions.

Lastly, I feel indebted to the many students I have had in my courses in signals and systems over the years I have

been teaching this material in the Department of Electrical and Computer Engineering at the University of Pittsburgh.

Unknown to them, they contributed to my impetus to write a book that I felt would make the teaching of signals and

systems more accessible and fun to future students in and outside the university.
