共四個部分18個單元，選材以電子通信技術的最新發展與應用為背景，電子信息工程領域涉及數字信號處理、圖像處理、口語系統、醫療電子、汽車電子、微波與集成電路設計等，通信工程領域包括數字通信、寬帶無線接入、光纖通信、4G移動通信、衛星通信和IPTV等，重點介紹基本概念、原理、方法與應用。實踐部分內容包括文獻檢索、英文摘要寫作及英語口頭報告。課文中穿插介紹科技英語語法知識，編排有豐富的習題并附習題答案和參考譯文。
《電子與通信專業英語（第2版）》可作為電子信息工程和通信工程專業本科生的教學用書，并適用于相近專業的本（專）科學生或具有一定英語基礎、對電子與通信工程專業英語感興趣的讀者，也可用做培訓教材和自學參考書。
專業英語是大學英語的一個重要組成部分，也是專業課程學習中的一門重要專業選修課，專業英語的學習為在高年級專業課學習中使用英語教科書或查閱英語參考文獻打下良好基礎。在科學技術飛速發展的今天，不僅要求學生在校學習期間具有扎實的英語基礎，還要求具有較強的專業英語綜合能力。專業英語的教學側重培養學生的專業文獻閱讀能力、科技英語寫作能力及專業語言交流能力，它是連接大學英語與雙語教學的橋梁，三者互為補充。為此，各高校在“重視基礎、強調實踐、擴大專業知識面、壓縮不必要學時數”的總的課程調整原則指導下，力求增加雙語課在專業課教學中的比重，使課程教學體系逐步與國際接軌。
本書遵循“重視基礎、強調應用、突出實踐”的編寫原則，課文主要節選自原版英文書籍或期刊雜志，力圖選擇內容新、實踐性強的材料，以提高學生的學習興趣，豐富專業領域新知識。全書分四個部分，共18個單元。第一部分為數學及電子學基礎。第二、三部分內容涉及電子與通信工程領域的各方面，側重融合新概念，介紹新應用。電子信息工程領域涉及數字信號處理、圖像處理、口語系統、醫療電子、汽車電子、微波與集成電路設計等，通信工程領域包括數字通信、寬帶無線接入、光纖通信、4G移動通信、衛星通信和IPTv等，基本覆蓋了電子與通信專業的主流方向，使學生掌握電子與通信工程專業的基本英文詞匯，為將來的學習及研究工作打下良好基礎。各單元由課文（包括詞匯表、難句注釋）、精選的科技英語語法知識、習題（其中習題1-3與課文有關，習題4復習語法知識）及閱讀材料組成，較好地解決了學生在學習過程中，因專業應用知識欠缺、科技文體不熟、語法特點了解不深入、專業詞匯量不夠所帶來的各種學習困難，為后續專業雙語課的學習掃除障礙。第四部分為實踐部分，作為面向應用型人才培養對專業英語教材改革的新嘗試，它也是本書的一個亮點，專題講授科技文獻檢索、科技論文中摘要的寫作及英語口頭報告等實用英語，強調學為所用，以期調動學生學習專業英語的積極性。

3. Translate the following sentences into Chinese.
（ 1 ） The calculus, aided by analytic geometry, proved to be astonishingly powerful and capable of attacking hosts of problems that had been baffling and quite unassailable in earlier days.
（2） Of the many remarkable mathematical discoveries made in the 17th century, unquestionably the most outstanding was the invention of calculus.
（3） A great forward stride was made in 1821, when the French mathematician Augustin Louis Cauchy developed an acceptable theory of limits, and then defined continuity, differentiability, and the definite integral in terms of the limit concept.
（4） Mathematical analysis is one of the most important divisions of higher mathematics; its main object is studying variables and their relationships.
（5） The main purpose of a natural or technical science is to establish the relationships between the variables involved in the process under consideration and to describe it mathematically.
（6） Mathematical methods lie in the foundation of physics, mechanics, engineering and other natural sciences. For all of them mathematics is a powerful theoretical and practical tool without which no scientific calculation and no engineering and technology are possible.Reading Material
Fourier Analysis and Synthesis
Jean Baptiste Joseph Fourier （1768——1830） studied the mathematical theory of heat conduction in his major work, The Analytic Theory of Heat. He established the partial differential equation governing heat diffusion and solved it using an infinite series of trigonometric functions. The description of a signal in terms of elementary trigonometric functions had a profound effect on the way signals are analyzed. The Fourier method is the most extensively applied signal-processing tool.This is because the transform output leads itself to easy interpretation and manipulation, and leads to the concept of frequency analysis. Furthermore even biological systems such as the human auditory system perform some form of frequency analysis of the input signals. The applications of the Fourier transform include filtering, telecommunication, music processing, pitch modification, signal coding and signal synthesis, feature extraction for pattern identification as in speech recognition, image processing, spectral analysis in astrophysics and radar signal processi
