Incorporating new problems and examples, the second edition of Linear Systems and Signals features MATLAB® material in each chapter and at the back of the book. It gives clear descriptions of linear systems and uses mathematics not only to prove axiomatic theory, but also to enhance physical and intuitive understanding.
Covers the conceptual and methodological aspects of signal processing clearly. Starts from an introductory level with each chapter providing a scaffold for later chapters without any large jumps.
Coming from a biological background, I thought I would be in for a rough time learning this content. However, the books makes signal processing accessible provided you have a reasonable foundation of mathematics.
Throughout my bachelor's and master's studies in electrical engineering this was by far my favorite book. Theory is explained very well and historical backgrounds for important breakthroughs were captivating. Even though it's been almost five years since I read it, I still remember with awe how impressed I was over the way Fourier series and transforms were explained. It seemed ludicrous to me that any periodic function could be expressed as a sum of sine waves. Excellent textbook!
This textbook is quite a good and comprehensive introduction to signals, systems, and signal processing. This is certainly not a short textbook, but much of the book is consumed by detailed and useful explanations of every topic therein. There are some topics that are not covered in as much depth as I would have liked, such as the existence of the Fourier transform for different types of signals and region of convergence of the Laplace and Fourier transforms for non-causal, two-sided, and anti-causal signals. However, the topics that are present are generally explained very clearly. I don't think it would be advisable to learn signals and systems with only such a textbook, but it is a valuable addition and a good reference material.
Very good book. It covers all the relevant theory on Signals and Systems and Differential Equations, and gives applications for all matters. It is full of examples and exercises, has some historical notes about the people who developed the ideias behind the theory and also some very funny comic strips about Engineering students! In my opinion it's one of the best books on the subject, despite some incoherence on the text and even some errors on examples, but it is certainly the most complete book about Signals and Systems.
It was a pretty good textbook. Only read & used Chapters 2-8 (of 10). For explanation and application of concepts into the engineering community, it was 5/5. The examples though were 4/5, for the fact that there were not a lot. Understanding though, that for some of the examples that did exist, there was quite a bit of content.
I would definitely say you could use this book to teach yourself these concepts, but you would have to have an additional resource to get a lot of more examples (and help explain exactly what some the problems are asking for).
This textbook is quite confusing; the illustrations rarely make sense and the examples do not help with the homework. The two stars come from the solution manual companion which is about twice as helpful as the textbook even though it often gets the problems wrong. Avoid if possible.
