This text presents the widely used techniques of signal and systems analysis with coverage of devices. Intended for beginning undergraduates with basic calculus, this book features a clear organization of topic beginning with convolution, and then moves on to extensive coverage of Fourier transforms. There are many examples of discrete system applications that students can easily follow. The second half of the text supplies coverage of one-two-sided Laplace transforms and analysis of discrete signals and systems by means of the z-transform. Students may 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.
