This Third Edition of a proven text presents the most widely used techniques of signal and systems analysis with superb coverage of devices. Intended for junior and senior students with basic calculus, this text features a clear organization of topics beginning with convolution, then moves to unusually extensive coverage of Fourier transforms. There are generous examples of discrete system applications that students can easily follow. The second half of the text supplies broad coverage of one- and two-sided Laplace transforms and analysis of discrete signals and systems by means of the z-transform. Students will benefit from state space material that has been expanded and rearranged to present the discrete case first, as well as an expanded learning system including solutions to all exercises plus an expanded appendix table with easy access to frequently encountered mathematical relationships used in signal analysis.

Appropriate for courses in Signals and Systems, and Transform Theory. This introductory text assists students in developing the ability to understand and analyze both continuous and discrete-time systems. The authors present the most widely used techniques of signal and system analysis in a highly readable and understandable fashion.

Introductory textbook on the fundamental concepts of continuous-time and discrete-time signals and systems, self-contained for independent or combined teaching approaches. Includes a CD-ROM containing MATLAB code and various signals. Contains worked examples, homework problems (solutions for instructors online) and extensive illustrations. Suitable for undergraduates in electrical and computer engineering.

This textbook offers a comprehensive survey of continuous and discrete time linear systems. It introduces and treats the topics separately to aid students' understanding and to allow the discrete time material to build naturally on the continuous time topics. Examples and applications are included.
