推荐一本书－－线性系统与信号    【作者】 （美）B.P.拉兹（B.P.Lathi ） 【出版社】 西安交通大学出版社 【内容简介】

《线性系统与信号》(第2版)对信号与系统给出了一种清晰的和综合理解性论述。本书通过启发式推理并利用各种比喻、模仿，以及一些创造性阐述用以强调各种概念的物理内涵。这种途径与单纯采用数学符号运算的纯演绎方法是完全不同的，它往往忽视了隐藏在各种推导背后的物理意义，这种演绎方法剥夺了一个学生从逻辑思维揭开事物本身而带来的愉悦感受。本书作者用了不太多的数学来证明公理性理论，用以支撑和增强物理的和直观的理解。只要有可能，理论上的结果都会以启发式的方式给予解释，并由精心挑选的例子和比拟给予深化。. 在讲授连续时间和离散时间概念方面，本书的组成还容许有更多的灵活性。各章的自然顺序是表明欲将连续时间和离散时间分析作为一个整体来对待的；然而，本书还可以裁剪成将这两部分按先后顺序进行。 由于全书整个内容，实际途径，以及结构上的可适应性，在大学本科“线性系统”或“信号与系统”课程中，《线性系统与信号》(第2版)是一本理想的教材。.. 本书全面系统地论述了线性系统与信号分析的基本理论和方法。全书除“背景知识”一章外共10章，内容包括：信号与系统，连续时间系统时域分析与拉普拉斯变换分析，离散时间系统时域分析与z变换分析，连续时间与离散时间信号的傅里叶分析，采样以及状态空间分析等。每章有足够数量的例题和附有答案的练习题，章末还有丰富多彩的习题。各章还配有单独的“MATLAB课时”供读者学习和应用。单立的“背景知识”一章汇集了本课程以及后续课程经常用到的一些基础知识和常用公式。

Book Description
Incorporating new problems and examples, the second edition of Linear Systems and Signals features MATLABRG 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.

About the Author
B.P. LATHI is Professor Emeritus of Electrical Engineering at California State University, Sacramento. He is the author of Signal Processing and Linear Systems (OUP, 2000) and Modern Digital and Analog Communications Systems, 3/e (OUP, 1998).

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.

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.
