This lavishly illustrated textbook has been designed so that students can perceive the basis of signal and linear system analysis procedures easily, enabling them to work a wide range of problems in linear systems. Key terms are concisely defined and easily identified. Approximately 200 thoroughly worked out examples are drawn mainly from an electrical engineering context. Contains nearly 500 end-of-chapter problems and the appendices include matrix properties and operations, mathematical and transform tables plus a computer program for FFT and IFFT computation.
Please, don't ever spend money to buy this book if you are trying to learn about signals and systems. This book is full of mistakes that are hard to catch if you don't have a professor telling you everything that was incorrect in the book. It is also extremely poorly written, so it is hard to encourage yourself to sit down, read and enjoy it. I'm not sure what other books to recommend you to so I apologize for that. If I ever find out, I'll try to remember to edit this comment with my other recommendation.
