Looking for signals/systems resources

Hi all,

I had a very distracted signals/systems prof who managed to make a difficult subject even harder. I did acceptably in the class, and I’ve gotten by on rules of thumb and simulation for 20 years, but my intuition and technical ability with anything but basic transfer functions is terrible and I want to improve. Do you have a favorite (preferably physical) reference for signals/controls that you like?


My professor was excellent in this field. He wrote a book but ironically didn’t teach from his book in class. I think that it was because of his humble personality:


I’ve never looked into this book at all but knowing the author, I suspect that it should be good and intuitive just like his teaching.

I’m a great fan of: http://www.dspguide.com/

The author is a talented DSP engineer (iirc he developed the backscatter machines used at airports), and the material is presented in a way that is easily digestible for engineers. Best of all, the book is available for free on the above website. Because you mentioned a physical copy, it is available as a textbook.

thanks! I’m okay with websites and PDFs, but I really learn best from physical books and re-doing proofs and derivations myself.

Second @Neal’s recommendation.

It’s available as a hardback book, too! Check the website for a link.

I also recommend Digital Signal Processing by Proakis and Manolakis.
