Signals and Systems 2nd Edition ISBN -978-0138147570

In addition to highlighting the similarities and differences between continuous-time and discrete-time concepts and methods, this thorough investigation of signals and systems also includes introductory treatments of the applications of these fundamental techniques in fields like filtering, communication, sampling, discrete-time processing of continuous-time signals, and feedback. The material is largely self-contained and presumes no prior knowledge of Laplace and z-transforms, convolution, Fourier analysis, or system analysis.
