Signals and Systems-Electrical Engineering

For sophomore/junior level signals and systems courses in Electrical and Computer Engineering departments. This text provides a clear, comprehensive presentation of both the theory and applications in signals, systems, and transforms. The text presents the mathematical background of signals and systems, including the Fourier transform, the Fourier series, the Laplace transform, the discrete-time and the discrete Fourier transforms, and the z-transform. The contents of each chapter are organized into well-defined units that allow instructors great flexibility in course emphasis.

NEW—MATLAB programs given in the examples are available at an Internet site and may be downloaded. Allows students to alter the data statements in these programs for the end-of-chapter problems.
NEW—Symbolic mathematics of MATLAB is used in verifying the calculations of transforms and in other appropriate applications.
NEW—Introduces the MATLAB simulation program SIMULINK to illustrate the simulation of continuous and discrete time systems.
NEW—Features many new problems; a majority of the end-of-chapter problems have either been altered or replaced. More than 50% of problems have been revised overall.
NEW—Contains short MATLAB programs in most examples. FEATURES
Relates the mathematical theory of systems and signals to practical systems.
<%1>Integrates the advanced features of the student version of MATLAB into the examples and problems. Symbolic mathematics is used to verify the calculations in the examples in the Fourier transform, the Fourier series, the Laplace transform, and the z-transform. The controls toolbox is used in the analysis of both continuous-time and discrete-time systems.<%-2>
Includes short sections on the bilateral Laplace and Fourier transforms for those instructors who wish to introduce the students to these topics.
Presents the Fourier series as an error-minimization result for approximating periodic signals with the sum of sinusoidal signals.
Includes chapters on state-variables for continuous-time and discrete-time systems.
Requires verification of results for almost all problems by an independent procedure, where appropriate. This includes, but is not limited to, MATLAB.
Repeats equations referenced, to prevent students from having to spend time thumbing back through the text.
Accompanied by a solutions manual for all problems available to instructors, in addition to disks containing the MATLAB programs used in the examples and required in the homework problems.
Provides over 300 homework problems and over 150 examples.
