Hi all, I will be studying Signals and Systems later this year and it would be great if you could recommend me some books, tell me why you prefer them over others and describe them a little. The contents of the course will be both time-continous and time-discrete signals, sampling, Z, Fourier and Laplace. As well as poles, zeros, filters and LTI systems. Some books I've been looking at: (some have been recommended here in other threads) Schaum's outline Signals and Systems by Oppenheim Linear Systems and Signals by Lathi Transforms in Signals and Systems by Kraniauskas About the books you suggest: Are they mathematically rigorous and thorough? Do they have much text and explanations or the other way around? Many examples? Diverse problems? Applications? Thanks!
