The study of signals and systems is basic to the discipline of electrical
engineering at all levels. It is an extraordinarily copious subject with
diverse applications. Indeed, a thorough understanding of signals and
systems is essential for a proper appreciation and application of other
parts of radio engineering, such as signal processing, communication
systems and control systems.
This book is intended to provide a modern interpretation of radio signals
and systems at an introductory level. As such, it is intended for use in
radio engineering curricula of the sophomore or senior students and is
designed to prepare the students for upper-level courses in
communication systems, control systems and digital signal processing.
The book provides a balanced and integrated interpretation of
continuous-time and discrete-time forms of signals and systems
intended to reflect their roles in engineering practice. Specifically, these
two forms of signals are treated side by side. This approach has the
pedagogical advantage of helping the student to see the fundamental
similarities and differences between discrete-time and continuous-time
representations. Real-world problems often involve the mixtures of
continuous-time an&d discrete-time forms, so the integrated treatment
also prepares the student for practical usage of these concepts.
Abundant use is made of examples throughout the book. All of these are
designed to help the student to understand and master th&e issues under
consideration.
Each chapter, except the last one, includes a large number of end-of-
chapter problems designed to test the student on the material covered in
the chapter. Another feature of the book is the emphasis given to desi&gn.
In particular, the chapters dealing with applications include illustrative
design examples.
MATHCAD (MATHematic Computer-Aided Design) has emerged as a
powerful environment for the experimental study of signals and
systems.
In making &this choice, we have been guided by the conviction that
MATHCAD provides a computationally efficient basis when the
concepts are explored and the system designs are tested.
