A comprehensive set of computer exercises of varying levels of difficulty covering the fundamentals of signals and systems. The exercises require the reader to compare answers they compute in MATLAB with results and predictions made based on their understanding of material. Chapter covered include Signals and Systems, Linear Time-Invariant Systems, Fourier Series Representation of Periodic Signals, The Continuous-Time Fourier Transform, The Discrete-Time Fourier Transform, Time and Frequency Analysis of Signals and Systems, Sampling, Communications Systems, The Laplace Transform, The z-Transform, Feedback Systems. For readers interested in signals and linear systems.
