This book is not clearly written. The discussion on Fourier and other math topics is a review, but if you knew those topics before you will be confused by the time you finish. There is often too little information in the text to answer the questions at the end of the chapter.

I had to use this book for one of my undergrad classes. It was not at all helpful. The material is presented in a very boring fashion with not enough explanation to do any hw problems on the material. The least it could do is do some examples that actually show you how they got the solution. The instructor did not help much either which made me hate communications.

I was hoping to find it sort of "full of well explained examples" resource, yet at this stage almost one year after passing the subject I believe this purchase was "unnecessary". For some reasons, the author keeps trying to "complexify" the topics which essentially are complex enough by themselves! while looking up if you're lucky you will see a short example of the topic that you're looking for and this happens like every 10 pages. Failure in digging into the topics and failure in explaining the issues with a simple language are the most significant problems that we experienced during the semester when using this book. I believe this subject needs a book with lots of examples and short but effective and right to the point explanations which sadly this book did not have.

I had a very strong intrest and like for the subject of communications before using this text. Fortunately, I don't judge subjects by a text or an instructor. I realize that just because an instructor or text is bad, does not mean that the subject is bad. In fact analog and digital communication is very intresting. The Schaum's Guide and the text written by B P Lathi are both excellently written and develops an appreciation and intrest for analog and digital communication. Couch's text, however is the worst that I have seen written on the subject. The first problem with Couch's text is the begining oder of presentation. He introduces pulse code modulation immediately after the Fourier series and transforms. AM and angle modulation(FM and PM) should have been presented after Fourier transforms. Also Couch acts as though he has never heard of the concept of modulation index, during his presentation of AM. The book has pages and pages of nothing but mumble jumble empty words. It does not teach you the subject. He hardly has any good examples relative to the problems at the end of the chapters. AM and FM should have been presented in seperate chapters. I cannot understand why anyone would recommend use of this text. The Schaum's Guide teaches the subject much better.

Seller claimed the condition of the book was new with some minor wear and tear. Once I received the book, I found a used book with a lot of pencil marks in the text. The condition was not what I expected. I decided not to return the book since I needed it for my work and I did not want to spend too much time trying to get my money back!

This book covers all the communication basics (analog and digital). I found it VERY useful to understand all the topics related to the Communication Systems course at University of Toronto

If you are new to communications, you may want to get a more in-depth exploration of the topics Couch covers (particularly the mathematics). I took this course at the University of Florida (although not with Couch). We were required to buy this book, but the instructor I had DIDN'T USE IT (school politics, I guess).

I didn't find it very helpful...not nearly enough examples.

You can find themes that dose not appear in other books. Every fragment is followed by an example.

Dr Couch does an excellent job of introducing the reader to analog & digital communications. Presenting an overview of such a subject is a daunting task
...yet he does so masterfully.

An invaluable part of my references and of others' personal "libraries." This book is an enduring cornerstone for understanding modern communications.

This is the worst book I was every forced to buy for my undergraduate degree. Bad examples, bad questions, just a very poor book. The idea of the class is good, but the way the information is presented is awful and you do not learn anything. The book assumes you know everything about circuits because it doesn't explain anything. Trust me VERY VERY BAD book from learning prospective.
