Summary: Excellent book to understand DSP basics
Comment: This book is the best available in market to understand the basics of Signal Processing with crisp explanations and very good mathematical treatment. Still I feel that, after reading this book one must switch to EITHER the book by Proakis and Manolakis OR the book by Oppenheim for more thorough knowledge. The knowledge gained from Prof Lathi's book makes others easy to comprehend. I would strongly recommend this book to any novice in Signal Processing domain.

Summary: Mathematically rigorous but explaining physical significance
Comment: This book clearly explains the physical significance of many phenomenon and topics that we come across in this subject. The most striking feature is that it does so from the fundamental linear differential equation and gives us very good insight of the subject and a sense of completeness . Definitely its better than Oppenheim book which deals the subject a bit more mathematical.

Summary: Better to get Oppenheim Schafer Buck
Comment: The Lathi book is fine, and covers both continuous and discrete signals, but is a little hard to read at times. A better book that covers both is the one by Oppenheim & Willsky. And if you want a much better book for the discrete side of things then get Discrete-Time Signal Processing by Oppenheim, Schafer, & Buck.

Summary: signal processing and linear system
Comment: this is a gem of a book on this subject no need to waste ur time reading abtruse and unfriendly books,the writer of this books comes down to the understanding of average student to explain the beautifull ideas of this subject.he is crystal clear about the subject and i have not found any book as good as this . he gives a good brushing up review in mathematics which is very very helpful.take my my advice ur money is safe in buying it .to do more numerical problems u can refer to A.V Oppenheim(a more difficult book).

Summary: Great Undergraduate Signals and Systems Textbook
Comment: This is truly a superior book for teaching Signals and Systems. It far outpaces the competition in my mind, especially in terms of conceptual descriptions, examples, and readability. It was the only text (I have looked at the most popular 6) that I found that is written in a coherent and readable manner, such that it could serve as a standalone self-paced tutorial.I am teaching this course for the first time this fall and found almost every one of my student's (and mine) conceptual and mathematical questions answered clearly by this text. I naively adopted Oppenheim since it is a classic, but that text truly pales in comparison.
Examples of things I appreciate in Lathi:
1) It serves as an excellent reference book, with a background mathematics section, tables of transforms and properties.
2) It generally starts each subject at the right point (e.g., with the trigonometic Fourier Series) to give student better conceptual understanding. I doesn't skip the basics.
3) It answers many common conceptual questions like "What is the meaning of negative frequencies in the FT?", "What do complex numbers mean physically?"
4) I love the history and wit (Is it a sin to make a textbook readable and even enjoyable?)
5) A lot of references to real engineering applications. For example, a REAL chapter on DIGITAL FILTER DESIGN.
I could go on, but it is obvious that the author put a great deal of care into this text and even the solutions CD. This, for upper-level undergraduate texts, in my opinion, is truly rare (see however, "Griffiths" and "Zahn" for E&M)
NOTE: By the way, for a previous reviewer, Ms. Chaston, in my text, the appendices are located on pages 161, 222, 356, 457, and 609.
Finally, I must admit that my own stupid prejudice cost me from adopting this textbook this year. I thought to myself, can a book written by a man with the name "Bhagawandas Pannalal" truly write this eloquently in English? As I get more in depth into the book, the answer is clearly YES and more.
