通信与信息工程专业英语教程

A business survives and thrives on information: information within the organization and information changed with suppliers, customers,and regulators. Moreover, the information needs to be consistent, accessible, and at the right location. We consider information in four forms-voice, data, image, and video-and the implications of distributed requirements.The term voice communications refers primarily to telephone related communications. By far the most common form of communication in any organization and for most personnel is direct telephone conversation. The telephone has been a basic tool of business for decades. Telephone communications has recently been enhanced by a variety of computer-based services, including voice mail and computerized telephone exchange systems. V oice mail provides the ability to send, forward , and reply to voice messages nonsimultaneously , and it has become a cost-efficient tool even for many midsize organizations. It provides saving on answering machines and services as well as more responsive service to customers and suppliers. Advances have also been made in computerized telephone exchange systems, including in-house digital private branch exchanges(PBX) and Centrex systems provided by the local telephone company. These new systems provide a host of features, including call forwarding, call waiting, least-cost routing of long-distance calls, and a variety of accounting and auditing features.The term data communications is sometimes used to refer to virtually any form of information transfer other than voice. It is sometimes convenient to limit this term to information in the form of text(such as reports, memos, and other documents) and numerical data(such as accounting files). The rapid changes in technology have created fresh challenges for management in making effective use of data communications. We will briefly outline the changes in technology in transmission, networks, and communications software that present the manager with new powerful business tools but also the necessity of making choices among complex alternatives.一个企业生存和蓬勃发展的信息：在改变与供应商，客户和监管机构的组织和信息的信息。

通信工程专业英语教程The field of communication engineering has experienced remarkable advancements in recent years, driven by the rapid technological progress and the ever-increasing demand for efficient and reliable communication systems. As the world becomes more interconnected, the role of communication engineers in shaping the future of global communication networks has become increasingly crucial. To meet the evolving needs of this dynamic industry, the development of a comprehensive and well-structured English curriculum for communication engineering majors is of paramount importance.The primary objective of an English curriculum for communication engineering students should be to equip them with the necessary language skills and technical knowledge to effectively navigate the global landscape of communication technologies. This curriculum should be designed to not only enhance their proficiency in English but also to provide them with a deep understanding of the specialized terminology, concepts, and methodologies relevant to their field of study.One of the core components of such a curriculum should be a strong emphasis on technical writing and communication. Communication engineers are often required to prepare technical reports, proposals, and presentations, which necessitate the ability to convey complex information in a clear, concise, and professional manner. The English curriculum should therefore include courses that focus on technical writing, report writing, and professional communication, providing students with the opportunity to develop these essential skills.In addition to technical writing, the curriculum should also incorporate language training that caters to the specific needs of communication engineers. This may include courses on academic English, scientific and engineering English, as well as English for specific purposes (ESP) courses that cover topics such as telecommunication systems, signal processing, and network protocols. By providing students with a solid foundation in the language used in their field, they will be better equipped to engage in discussions, read and comprehend technical literature, and collaborate with international colleagues.Another crucial aspect of the English curriculum for communication engineering majors should be the integration of project-based learning. This approach allows students to apply their language and technical skills in real-world scenarios, fostering their ability to work in teams, solve complex problems, and communicate effectively withdiverse stakeholders. Such projects may involve the design and implementation of communication systems, the analysis of network performance, or the development of innovative communication technologies.Furthermore, the curriculum should incorporate opportunities for students to engage in international collaborations and exchanges. This could include student exchange programs, virtual international team projects, or participation in global communication engineering conferences and workshops. These experiences not only enhance students' language proficiency but also expose them to different cultural perspectives and industry practices, preparing them for the global nature of the communication engineering field.To ensure the effectiveness of the English curriculum, it is essential to incorporate ongoing assessment and feedback mechanisms. This may include regular evaluations of students' language proficiency, technical knowledge, and communication skills, as well as feedback from industry partners and alumni to ensure the curriculum remains relevant and responsive to the evolving needs of the communication engineering sector.In conclusion, the development of a comprehensive English curriculum for communication engineering majors is a crucial step in preparing the next generation of communication professionals. Bycombining language instruction with technical knowledge and practical application, this curriculum will equip students with the necessary skills and competencies to thrive in the dynamic and globally interconnected world of communication engineering. As the demand for efficient and innovative communication systems continues to grow, the importance of a well-designed English curriculum cannot be overstated, as it will contribute to the development of highly skilled and globally-minded communication engineers who can drive the future of the industry.。

信息与通信工程专业英语(第2版)韩定定李明明第一课现代数字设计及数字信号处理课文 A: 数字信号处理简介1.什么是数字信号处理？数字信号处理，或DSP，如其名称所示，是采用数字方式对信号进行处理。

在这种情况下一个信号可以代表各种不同的东西。

从历史的角度来讲，信号处理起源于电子工程，信号在这里意味着在电缆或电话线或者也有可能是在无线电波中传输的电子信号。

然而，更通用地说，一个信号是一个可代表任何东西--从股票价格到来自于远程传感卫星的数据的信息流。

术语“digital”来源于“digit”，意思是数字（代可以用你的手指计数），因此“digital”的字面意思是“数字的，用数字表示的”，其法语是“numerique”。

一个数字信号由一串数字流组成，通常（但并非一定）是二进制形式。

对数字信号的处理通过数字运算来完成。

数字信号处理是一个非常有用的技术，将会形成21世纪的新的科学技术。

数字信号处理已在通信、医学图像、雷达和声纳、高保真音乐产生、石油开采等很广泛的领域内引起了革命性的变革。

这些领域中的每一个都使得DSP 技术得到深入发展，有该领域自己的算法、数学基础，以及特殊的技术。

DSP发展的广度和深度的结合使得任何个人都不可能掌握已发展出的所有的DSP技术。

DSP教育包括两个任务：学习应用数字信号处理的通用原则及学习你所感兴趣的特定领域的数字信号处理技术。

2.模拟和数字信号在很多情况下，所感兴趣的信号的初始形式是模拟电压或电流，例如由麦克风或其它转换器产生的信号。

在有些情况下，例如从一个CD播放机的可读系统中输出的信号，信号本身就是数字的。

在应用DSP技术之前，一个模拟信号必须转换成数字信号。

例如，一个模拟电压信号，可被一个称为模数转换器或ADC的电路变换成数字信号。

该转换器产生一系列二进制数字作为数字输出，其值代表每个采样时刻的输入模数转换设备的电压值。

3.信号处理通常信号需要以各种方式处理。

例如，来自于传感器的信号可能被一些没用的电子“噪声”污染。
