This book gives an introductory treatment of signals and systems and is
intended to be used as a text for students of electrical and electronic engineering.
It is based on the experience of teaching circuits, signals and systems at the
Faculty of Electrical and Electronic Engineering as well as the International
Faculty of Engineering of the Technical University of Lodi. It is assumed that
the reader has some knowledge of complex numbers and functions, basic
electrical engineering and circuit theory. These prerequisite skills are mastered
by the students during the junior years. The book should also be useful to
engineers, enabling them to update and enhance their knowledge of signals and
systems through self-study. Since the book is addressed to the electrical and
electronic engineering students the material contains, beside the standard subjects
of signals and systems, also analog-filter and digital-filter design. For the same
reason numerous examples used to illustrate the theoretical material ref er to
electric and electronic circuits and systems.
The book includes a large number of examples. They are provided to illustrate
the concepts and to make the theory more understandable. Furthermore, the
examples enable the students to master some techniques and analysis tools and
learn to use them effectively.
Throughout the book linear, time-invariant systems are studied and
continuous-time as well as discrete-time signals and systems are considered
simultaneously as much as possible.
The book provides the fundamentals of signals and systems and gives a
background for later signal processing studies. A brief outline of this material is
as follows.
Chapter I presents an introduction to continuous-time and discrete-time
signals and systems. It provides preliminary concept, basic definitions, and
mathematical techniques including the continuous and discrete convolution.
Chapter 2 is devoted to the Laplace transform and its application to circuit
analysis. It examines in detail basic properties, rules, and techniques of the
Laplace transform and derives the operator method for the analysis of linear
circuits and systems. The results of Chapter 2 are extended in Chapter 3 where
the concept of transfer function of continuous systems is introduced and block
diagrams and signal-flow graphs enabling to determine transfer functions are
discussed.
Starting from Chapter 4 we consider frequency-domain descriptions of
signals. Fourier series representation for continuous-time signals is included in
Chapter 4. Chapter 5 exploits Fourier series to the analysis of systems driven by
periodic excitations. The discrete Fourier series is introduced in Chapter 6.
Discrete Fourier transform is developed in Chapter 7 and its effective
implementation, known as the fast Fourier transform, is discussed in Chapter 8.
Chapter 9 presents in detail the Fourier transform of continuous-time signals
whereas Chapter 10 deals with the Fourier transform of discrete-time signals.
Some applications of the Fourier transform, including sampling of continuoustime
signals, and amplitude modulation, are given in Chapter 11. The concepts of
signal energy and power are developed in Chapter 12.
Chapter 13 is devoted to the Z-transform of discrete-time signals; it discusses
basic properties and introduces the transfer function of a discrete system.
The final two chapters are focused on design of analog and digital filters. Both
mathematical background and some techniques of design of the analog
Butterworth and the Chebyshev filters are developed in Chapter 14. The design
techniques of digital filters are presented in Chapter 15. Window approach for
designing FIR filters is discussed and bilinear transformation as well as the
impulse-invariance technique for designing IIR filters are developed.[...]
