B. P. Lathi's trademark strengths as a writer have made this introductory volume a well-established leader in the field of signals and linear systems. His rigorous but clear explanations, engaging writing style, vivid examples, and sensitivity to student needs enliven the subject in a comfortable non-threatening way. Now published by Oxford University Press, Linear Systems and Signals provides a comprehensive treatment of the subject and encourages students to discover information and principles on their own. Lathi uses mathematics to enhance physical and intuitive understanding, instead of merely employing it to prove axiomatic theory. The book is conveniently organized into five parts that allow flexibility in teaching discrete-time and continuous-time systems. An accompanying solutions manual is available on CD-ROM.
Reviews:
This is one of the few highly readable textbooks I own. I sit down and read the narrative of the author without instantly falling asleep. This fourth edition features two big new additions: expanded MATLAB instruction and a comprehensive review chapter. This review chapter refreshes the reader on topics essential to understanding concepts throughout the book. Complex numbers, sinusoids, matrices, partial fraction expansion (which is repeated ad nauseam throughout the text) and more are all throughly taught in this review chapter, which makes up 67 of the book's 900+ pages. Do be warned: this thick book will eat up space in your bag. The new MATLAB sections were authored by my professor, Dr. Roger Green. It was amusing to read his foreword because his tone on paper is identical to his lectures. If you find yourself assigned lots of MATLAB work, I only hope you have a professor as knowledgeable in it as Dr. Green. Otherwise you may be in for some confusion; I'm glad I had access to the author! Overall, the MATLAB section is well-done, and the author states it's light-years better than previous versions. I really did improve my MATLAB skills while using this book. I am choosing to keep this book for future reference and not sell it back to the school or to next semester signals students. This is the best testimony I can give to the effectiveness of this book. Thankfully, I had a very thorough teacher who covered the topics in good detail. However, numerous times he simply said, "read the book, it does a better job at explaining than I could do." The MATLAB sections and the readability factor will keep this book on my shelf for many years.
This book though lucid in its conversational language does not explain how the author came to his conclusions. Gives examples that the solutions of which are not traceable to the method described and is dirth of the supposed answers to exercises included. As a required text it is a nightmare to an engineering student required to take this couse as a introduction to the subject. David M. Cook (actual name)
This book has it all: logic, concepts, math, many examples, practical applications, even little historical notes and matlab sections. It's just a very accurate, neat, and well organized book. The guy actually exlains "why". He explains not only how to DO Laplace, Fourier, etc but how to UDERSTAND it. And he is very accurate with what and how he is saying. I bought this book for my undergrad systems and signals class for extra reading and thanks to this book it wasn't one of those 'mechanically' learned classes but math actually acquired meaning.
Lathi's book is an excellent, easy-to-read and easy-to-understand text on systems and signals. He spends a lot of time explaining in-depth examples, doing so without assuming the student has insight he or she probably does not-a common problem in other textbooks. Lathi goes out of his way to explain every nuance, greatly helping the learning processs Unlike most other textbooks, this one is easy to read, without a glut of technical jargon, or pages and pages of mathematical formulae without text explaining where the author is heading. Lathi also includes a very comprehensive background section, polishing and reviewing the mathematical techniques necessary for solving the problems. It is handy to have this in one book, rather than require trigonometry, matrix algebra, and differential equations books at the standby for review. One complaint is that this book does not have solutions to some of the homework problems, helping with additional study. This isn't quite the problem it is in other books since the examples are very thorough and insightful. Simply put, not only is this probably the best textbook on systems and signals, it is one of the best textbooks I have ever used.
The author is really solid. He writes his text carefully. You won't find a higher quality, more coherent book on the subject when it comes to systems. The best part is the fist half, the first 6 chapters on system analysis. The second half, signal analysis, is also quite good, but a bit harder to understand and follow than the first half. It is still far better than just about every other book out there... except for Peter Kraniauskas' book, "Transforms in Signals and Systems," which is the best choice for understanding signal analysis. I highly recommend getting both Lathi's book and Peter's book if you can afford it. If you can only afford one book, you are a first time student in systems and signals, or you are interested mainly in circuits, filters, transfer functions, frequency and phase responses and so forth, go with Lathi's book. If you can only afford one book, and you are interested in DSP with Fourier analysis, and discrete Fourier analysis, as well as spectrum analysis in general, go with Peter Kraniauskas' book. In Summary: If you are in a class called "Systems and Circuits" or something like that, get Lathi's book. If you are in a class called "Discrete Time Signals and Systems" or "Frequency Analysis", go with Peter's book.
