通信工程专业英语课文翻译
Technology of Modern CommunicationText A: BluetoothBluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable（轻便的）and fixed devices while maintaining high levels of security.The key features of Bluetooth technology are robustness（稳健）, low power, and low cost .The Bluetooth specification defines a uniform structure for a wide range of devices to connect and communicate with each other.蓝牙无线技术是一种小范围无线通信技术，旨在保持高安全级的基础上，在便携式设备与固定设备之间实现无线连接。
蓝牙技术的主要特点是稳健，低功耗和低成本。
蓝牙规范定义了一个统一的结构，适用范围广的设备连接并相互沟通。
Bluetooth technology has achieved global acceptance such that any Bluetooth enable device, almost everywhere in the world, can connect to other Bluetooth enabled devices in proximity. Bluetooth enabled electronic devices connect and communicate wirelessly through short-range, ad hoc（特别）networks known as piconets Each device can simultaneously communicate with up to seven other devices within a single piconet. Each device can also belong to several piconets simultaneously. Piconets are established dynamically and automatically as Bluetooth enabled devices enter and leave radio proximity.蓝牙技术已取得全球认可，使得任何支持蓝牙的设备，几乎在世界各地，可以连接到其他支持蓝牙的邻近装置。

通信工程专业英语TEXT1信息的数字表示
The key advantage of digital representation lies in the universality of representation. Since any medium, be it a text, an image, or a sound, is coded in a unique form which ultimately results in a sequence of bits, all kinds of information can be handled in the same way and by the same type of equipment.Furthermore, transformations of digital information are error free, while analog transformations introduce distortions and noise.1 StorageThe same digital data storage device can be used for all media. The only difference may lie in size requirement.Still images and motion video require larger volumes than text or graphics. Sound also is demanding though less so than imaging. Thus, appropriate digital devices may be required, such as compact disk-read-only memories (CD-ROMS). But the key point is that a single type of digital device may store all kinds of information.2. TransmissionAny data communication system capable of carrying bits has the potential to transmit any multimedia digital information. Thus, a single communication network supporting digital transmission can, in theory, be envisaged.This concept is referred to as an integrated services digital network （ISDN), which is a facility aimed at integrating the transport of all information media.The difficulties may arise from the requirements of certain applications, in particular those which need to respect with fidelity（忠实、保真度）the time-dependency of digital signals.Even when the potential for integrating different types of information on a single communication system is not exploited, the benefits of digital versus analog transmission are numerous. First, digital signals are less sensitive to transmission noise than analog signals.Second, the regeneration of the signal--which is the process by which an attenuated signal is strengthened -- is easier. Third, error detection and correction can be implemented. Fourth, the encrypting of the information is also easier.3. ProcessingAs all information is stored on computers, it can be processes, analyzed, modified, altered, or complemented by computer programs like any other data. This is probably where the potential is the highest.•An attempt may be made to recognize semantic contents (speech, handwriting, form, and pattern recognition). An example of advanced contents recognition is the detection of cuts in motion video to automatically identify and index video sequences.•Data structures, chaining using pointers between information elements, may be created for faster and flexible retrieval（检索）.•Powerful editing by cut-and-paste functions to create monomedia (e.g. sound only) or multimedia documents is possible.•The quality of information may be improved by the removal（移除）of noise or errors as shown by the digitization of old vinyl records to create higher-quality audio compact disks.•Information of a similar type but created through different processes---such as motion imaging synthesized by computers and camera-captured video--- may be mixed.•To summarize:•Digital representation permits the storage of different information types on the same device. Information may also be transmitted over a single digital network.Likewise, when digitized, all forms of information may be treated by computer programs, for editing, quality improvement, or recognition of the meaning of the information.4. Drawback (缺点，不足）of Digital Representation of Continuous InformationThe major drawback of the digital representation of information lies in coding distortion. The process of first sampling and then quantizing and coding the sampled values introduces distortions. As a result, the signal generated after digital-to-analog conversion and presented to the end-user has little chance of being completely identical to the original signal.Increasing the sampling rate and multiplying the number of bits used to code samples reduces the distortion. The result is an increased number of bits per time or space unit, called bit rate, necessary to represent the information. There are clearly technological limits to the explosion of bit rates: storage capacity is not infinite, and transmission systems also have limited bandwidths.One of the key issues then is to choose an appropriate balance between the accuracy of the digitization, which determines the bit rate, and the perceived（感知，觉察）distortions by users. Do not forget that it is how distortions are perceived by humans which matters, not whatthey are physically.Another consequence, as mentioned before, is the need for a large digital storage capacity for moving or still images and, to a lesser extent, for sound. Eight minutes of stereophonic CD sound are enough to completely fill（装满）the 80 megabyte hard disk of a standard personal computer.Fortunately, compression algorithms have been developed to alleviate（缓和，减轻）these requirements. But only spectacular recent progress in digital storage capacity and cost has enabled the development of massive digital storage of media such as images, sound, and motion video.Let us summarize:The digitization process introduces a distortion of the information. Reducing this distortion may be achieved by increasing the sampling rate and the number of bits to code each sample. Images, sound, and motion video require a large amount of digital storage capacity.给大家推荐一个英语微信群Empty Your Cup英语微信群是目前学习英语最有效的方法，群里都是说英语，没有半个中文，而且规则非常严格，是一个超级不错的英语学习环境，群里有好多英语超好的超牛逼的人，还有鬼佬和外国美眉。
