Book Description

August 16, 1996 0138147574 978-0138147570 2

This authoritative book, highly regarded for its intellectual quality and contributions provides a solid foundation and life-long reference for anyone studying the most important methods of modern signal and system analysis. The major changes of the revision are reorganization of chapter material and the addition of a much wider range of difficulties.

Editorial Reviews

Amazon.com Review

The second edition of this well-known and highly regarded text can be used as the basis for a one- or two-semester undergraduate course in signals and linear systems theory and applications. Topics include basic signals and systems concepts, linear time-invariant (LTI) systems, Fourier representations of continuous-time and discrete-time signals, the CT and DT Fourier transforms, and time- and frequency-domain analysis methods. The author emphasizes applications of the theory through numerous examples in filtering, sampling, communications, and feedback. The parallel development of continuous-time and discrete-time frequency domain methods allows the reader to apply insights and intuition across the two domains. It also facilitates a deeper understanding of the material by bringing into focus the similarities and differences between the two domains. The text also includes introductory chapters on communication systems and control theory. This book assumes that you have a background in calculus as well as exposure to complex numbers and elementary differential equations. Because of its thoroughness and unhurried pace, this text is highly recommended for students and those interested in self-study.

From the Publisher

This comprehensive exploration of signals and systems develops continuous-time and discrete-time concepts/methods in parallel -- highlighting the similarities and differences -- and features introductory treatments of the applications of these basic methods in such areas as filtering, communication, sampling, discrete-time processing of continuous-time signals, and feedback. Relatively self-contained, the text assumes no prior experience with system analysis, convolution, Fourier analysis, or Laplace and z-transforms.

4.0 out of 5 stars Enjoyable but sometimes unclear March 20, 2007
By Abraham
Format:Hardcover
This is one of my favorite books I've covered in my undergraduate degree.

I've noticed several previous reviewers have critisized this book based on clearly false assumptions. Clarification must be done for non-EEs:

This book, along others titled ' Signals and Systems' is intended as a preliminary to the 'systems' part of electrical engineering in general(namely Communications, Signal Processing, and Control). Hence it's not a book on standard DSP (the author has two other books that are specifically entitled Digital Signal Processing and Discrete time signal processing).

What's more, since this book was designed specifically as an introduction for sophomore and junior engineering students, one cannot expect this book to go into lebesgue2 space, inner-products, bounded-operators and the like. Certainly oppenheim didn't have functional analysts in mind when he wrote this book! The mathematically inclined reader should aim for 'Signal Analysis: Time, Frequency ,Scale, and Structure' by Allen and Mills.

As for the typical reader of this book, I think it is well written and the equations are very well motivated. The author repeats the difficult and essential concepts several times here and there, which is very useful for the new comers into the field, although I do agree with reveiwers that said the book needs some adjustments in terms of examples, which are sometimes trivial and sometimes confusing.

I believe the book needs to be updated by the author sometime. The book lacks computer problems and examples, which would be very helpfull for students to visualize what's going on.

hope this was useful!

5.0 out of 5 stars Many other reviews not fully objective??? November 6, 2001
Format:Hardcover
I have just used this text in teaching a second-year Signals and Systems course. Yes -- the students have struggled with the course, and several of them have grumbled about the book. However, none of the adverse comments I've received about the book either from my students or other reviewers here seem to be valid. The possible exception is the lack of more worked examples or at least answers to end of chapter problems.
The book is an excellent basic introduction to the subject. It takes what can be a very difficult subject for students and provides a relatively clear path through the material. It doesn't assume very much mathematical background in the sense that there are plenty of very elementary problems in chapter one to remind you of the basics that you need for the rest of the book. Obviously if students have trouble with these problems they need to consider additional study to fill in some of the gaps in their knowledge on the mathematics side.
The worked examples in the chapters are excellent, although sometimes you have to ask yourself what you are supposed to be learning from each example or end of chapter problem. The first 20 problems at the end of each chapter really cover the chapter material, and subsequent problems delve into the material in a little more depth or in relation to more real-world problems. If you understand the chapter you should have no great difficulty in doing the first 20 problems in each chapter, and the answers are provided to help you make sure you aren't missing the point. I found some of the other problems a little less clear, and certainly the students had difficulties here. I provided well over a hundred pages of written solutions for my students to try to overcome this deficiency.

4.0 out of 5 stars Excellent introduction to the topic June 25, 2003
Format:Hardcover
Having had this book for 2 semesters in a Signals and Systems course, I can say that it has done its job in presenting an in-depth and clear introduction to the topic. It is well-written, structured, comprehensive and has lots of challenging (and not so) exercises and examples.
A few comments on the latter: it seemed to me that the first 20 basic exercises at the end of each chapter were very basic, of the type "plug-in the formula from the table on the previous page", while the subsequent problems, especially the advanced ones, are way above the level of the former. Working out through those was meticulous, hard and very lengthy as compared to the basic stuff (the solutions provided by our instructor were of the order 1-2 typed pages per problem). Providing answers or at least general strategies would have been tremendously helpful. I am aware that there is a solutions manual, however the textbook itself is expensive enough.
The information was presented clearly, but I liked our professor's introduction to convolution more that the book's coverage. The sampling chapter was, at least to me and some of my fellows, a bit confusing and we had to, again, rely more on class notes.
Overall this is a good book, albeit very-very expensive (I was lucky enough to get a cheap Indian reprint).

3.0 out of 5 stars Needs better explanations and examples January 16, 1999
Format:Hardcover
Although widely accepted as the standard text for introductory signals & systems courses, this book is sometimes unclear and difficult to read. Chapters covering introduction to LTI sytems and convolution theory are poor and confusing. Chapters covering continuous Fourier transform and sampling are pretyy good, however. The way in which the text shifts back and forth from continuous to discrete systems is annoying and not likeley to be useful in an actual course.
