About the Author

Jamal T. Manassah, has been Professor of Electrical Engineering at the City

College of New York since 1981. He received his B.Sc. degree in Physics from

the American University of Beirut, and his M.A. and Ph.D. in Theoretical

Physics from Columbia University. Dr. Manassah was a Member of the Insti-

tute for Advanced Study. His current research interests are in theoretical and

computational quantum and nonlinear optics, and in photonics.

Introductio n

This book is mostly based on a series of notes for a primer course in electrical

and computer engineering that I taught at the City College of New York

School of Engineering. Each week, the class met for an hour of lecture and a

three-hour computer laboratory session where students were divided into

small groups of 12 to 15 students each. The students met in an informal learn-

ing community setting, a computer laboratory, where each student had the

exclusive use of a PC. The small size of the groups permitted a great deal of

individualized instruction, which was a key ingredient to cater successfully

to the needs of students with heterogeneous high school backgrounds.

A student usually takes this course in the second semester of his or her

freshman year. Typically, the student would have completed one semester of

college calculus, and would be enrolled in the second course of the college

calculus sequence and in the ﬁrst course of the physics sequence for students

in the physical sciences and engineering.

My purpose in developing this book is to help bring the beginner engineer-

ing student’s analytical and computational skills to a level of competency

that would permit him or her to participate, enjoy, and succeed in subsequent

electrical and computer engineering courses. My experience indicates that

the lack of mastery of fundamental quantitative tools is the main impediment

to a student’s progress in engineering studies.

The speciﬁc goals of this book are

1. To make you more comfortable applying the mathematics and

physics that you learned in high school or in college courses,

through interactive activities.

2. To introduce you, through examples, to many new practical tools

of mathematics, including discrete variables material that are

essential to your success in future electrical engineering courses.

3. To instruct you in the use of a powerful computer program,

MATLAB ® *, which was designed to be simultaneously user-

friendly and powerful in tackling efﬁciently the most demanding

problems of engineering and sciences.

4. To give you, through the applications and examples covered,

glimpses of some of the fascinating problems that an electrical or
