Signals and Systems – Alan Oppenheim – 2nd Edition


The second edition of this well-known and respected text can be used as the basis for a one semester or two undergraduate course in Signals and Theory of Linear Systems and Applications.

Topics include signals and basic concepts of systems, time invariant linear systems (LTI), Fourier representations of continuous time and discrete time signals, the CT and Fourier DT transforms, and the time and frequency domain of analysis.

The author emphasizes the applications of theory through numerous examples in filtering, sampling, communications and retrofeeding. The parallel development of continuous time and discrete time domain methods allows the reader to apply ideas and intuition across the two domains. It also facilitates a deeper understanding of the material by focusing on the similarities and differences between the two domains.

The text also includes introductory chapters on communication systems and theory. This is supposed to have a background calculation, as well as exposure to complex numbers and elementary . Due to its thoroughness and slow pace, this text is highly recommended for students and people interested in self-.
