編輯推薦

“信號與係統”是包括電氣工程、電子信息工程、通信工程和自動化等本科專業重要的專業基礎課程之一。本教材對應於全國雙語示範課程。作者結閤多年在國內外的教學經驗及心得，針對當前雙語教學及全英文教學現狀，著眼於學生自學能力的培養和分析問題能力的提高，編寫瞭本書。

本書側重培養學生分析問題的能力及注重研究問題方法的學習。與現有同類中英文教材相比：

（1）文字精煉，內容安排上采用模擬-離散雙域交替的方式。

（2）在處理常係數綫性微分（差分）方程及由其描述的綫性時不變係統及與變換的關係上有獨到之處。

（3）知識體係完整，係統及邏輯性強，同時也適用於自學。

內容提要

Fundamentals of Signals and Systems deals with the concepts of signals and systems, which are the corner-stone of a wide variety of areas ranging from home-oriented consumer electronics and multimedia entertainment products to sophisticated munications, aeronautics and astronautics, and control. A course on signals and systems is fundamental and pulsory for an engineering under-graduate curriculum in any well-established tertiary (education) institutions. This book provides readers with the basic principles and methods underlying the analysis of signals and systems in the context of both continuous- and discrete-time, including Fourier analysis based representations for signals and both time- and transform-domain approaches as well as state-space approach to (linear time-invariant) systems. Great emphasis is placed on being concise, easy for self-study, and rigorous. Compared with most of the existing textbooks on the same topics, more effort is made in this book to provide a clear picture of the relationship between linear constant differential/difference equations and linear time-invariant systems. Another significant feature of this book is a separated chapter (Chapter 8) that contains a set of prehensive exercises, each of which usually involves mathematical deviations and more sophisticated application of the concepts and approaches provided in the entire text book rather than an individual chapter. This book is primarily designed for undergraduate students majoring electrical & electronics and information engineering, the concepts and techniques introduced in the book, however, are of fundamental importance in all other engineering disciplines. Readers of this book are assumed to have a basic background in engineering mathematics, including calculus, plex functions, and linear differential equations. Some knowledge on circuit theory, though not a prerequisite, would be helpful for the study.

序言

Preface

Theconcepts of signals and systems are the corner-stone of a wide variety ofareas, ranging from home-oriented consumer electronics and multimediaentertainment products to sophisticated munications, aeronautics andastronautics, and control. The ideas and approaches associated with theseconcepts have great e.ects on our life in one way or another. Although thesignals and systems which arise across those .elds are naturally di.erent intheir physical make-up and application, the principles and tools for analyzingsignals and systems are the same and hence applicable to all of them.Therefore, an introductory course on signals and systems is fundamental andpulsory for an engineering under-graduate curriculum in any well-establishedtertiary (education) institutions. Such a course is monly designed in one ofthe two forms below:

.  aone-semester subject that intends to provide students with a rich set ofconcepts and tools for analyzing deterministic signals and an important classof systems known as linear time-invariant systems;

. atwo-semester subject that expands on the one-semester course by adding moredetailed treatment of signal processing and systems for speci.ed applicationssuch as munications, multimedia signal processing and control engineering. 

Thisbook takes the .rst form and assumes that the students have a background incalculus and introductory physics.

Whyanother “Signals and Systems”

Giventhat there are many well-written textbooks on signals and systems available,our readers would be screaming when seeing this textbook: Why another “Signalsand Systems”

Thethought of writing such a textbook was stimulated in 2007 when the .rst authorconducted a 2nd year course on signals and systems in Zhejiang University ofTechnology (ZJUT) in Hangzhou, which he just joined from Nanyang TechnologicalUniversity (NTU), Republic of Singapore. The course was designed as ¡°shuang yuke¡± spelled in Chinese, meaning that the teaching materials such as thetextbooks and slides are all in English and as to the class language, thelecturers can choose either Chinese, English or a mixture of the two¡ªa typicalChinese style! The textbooks adopted were those popularly used in the world butwere found very di.cult to most of our students as their English is not goodenough to deal with those textbooks of one thousand pages or so in length.1This motivates him to write a new “Signals and Systems”

Here,we have those big masters of Signals and Systems to “blame” why not writingtheir text-book in Chinese!

with aprimary objective of providing a condensed version of “Signals and Systems”in English, while keeping the important technical materials as much aspossible.

Mostof us agree that for a university study it is more important to teach studentshow to learn and analyze than what to be learned and analyzed. The .rst authorstill remembers what was said by Professor Y. Liu who taught him calculus in1978 in Beijing Institute of Technology (BIT) (now, known as Bei Li Gong) thata good textbook, say of ten chapters, should be written in such a way thatafter the .rst four chapters taught by the lecturer, the rest can be studied bystudents themselves easily. What Prof. Liu really meant is that a textbookshould be written to facilitate and reinforce self-study. This is anotherobjective that this textbook is intended to achieve. Given the mathematicalnature of this subject, rigidity should be sustained as much as possible, whichis something very important to engineering students to learn. This is the thirdobjective of this textbook.

Howthe book is structured

One ofthe reasons for the existing textbooks of signals and systems to have easilyover eight hundred pages is due to the continuous-and discrete-time forms ofsignals and systems. The success of a signals and systems that achieves ourprimary object lies in how to provide a balanced and integrated treatment ofthe two forms in a pedagogical way that can help students see the fundamental similaritiesand di.erences between the two without too much repeating. With all of these inmind, this book is organized as follow.

.   Chapter 1 is aimed to provide an overview ofsignals and systems. Compared with the one in most of the signals and systems,it is condensed with an emphasis on the periodical signals and lineartime-invariant (LTI) systems. 

.   Chapter 2 deals with the time-domain approachto the LTI systems. Since the key to the development of this chapter is toexploit the properties of linearity and time-invariance as well as signaldepositions, the concepts of unit impulse re-sponse and convolution aredeveloped in details for the discrete-time case, while the continuous-timecounterparts are directly given. One of the remarkable points emphasized inthis chapter is the equivalence between the LTI systems and con-volutions,which relates the physical interpretation and mathem 信號與係統基礎(高等學校電子信息類專業係列教材) 下載 mobi epub pdf txt 電子書 格式
