电子信息工程专业英语教程_第5版 模拟试卷AB卷及答案
Technical English Test for Electronic Information EngineeringDepartment____________ Class___________ Name____________SECTION 1Fill in the blanks with proper terms (30 minutes).SECTION 2Translate the following passages into Chinese (40 minutes).1.Digital signal processing tasks can be performed by all processors. Specialized digital signalprocessors (DSPs), however, perform these tasks most efficiently and most quickly. While traditional processors follow the V on Neumann architecture model, which assumes a shared single memory to be used for both program instructions and data, DSPs use the Harvard or modified Harvard architecture, which includes multiple program and data memories, along with multiple buses to access them.2.The basic services that the IMT-2000 network is supposed to provide to its users are: 1.High-quality voice transmission. 2. Messaging (replacing e-mail, fax, SMS, chat, etc.). 3.Multimedia (playing music, viewing videos, films, television, etc.). 4. Internet access (Web surfing, including pages with audio and video).3.The image sensor employed by most digital cameras is a CCD. Some low-end cameras useCMOS technology. While CMOS sensors will almost certainly improve and become more popular in the future, they probably won't replace CCD sensors in higher-end digital cameras.4.Make sure the camera has the right resolution for your needs. If you are going to take snapshotsand e-mail them to friends, then you don't need anything more than 640x480 pixel resolution.Buying the resolution that you need lets you save money (and hard disk space). On the other hand, if you want to print enlarged versions of your photos, you'll need a 2-megapixel or 3-megapixel camera.SECTION 3Read the following passages and answer questions (30 minutes).Passage oneCD-quality audio requires a transmission bandwidth of 1.411 Mbps. Clearly, substantial compression is needed to make transmission over the Internet practical. For this reason, various audio compression algorithms have been developed. Probably the most popular one is MPEG audio, which has three layers (variants), of which MP3 (MPEG audio layer 3) is the most powerful and best known. Large amounts of music in MP3 format are available on the Internet, not all of it legal, which has resulted in numerous lawsuits from the artists and copyright owners. MP3 belongs to the audio portion of the MPEG video compression standard.Audio compression can be done in one of two ways. In waveform coding the signal is transformed mathematically by a Fourier transform into its frequency components. The amplitude of each component is then encoded in a minimal way. The goal is to reproduce the waveform accurately at the other end in as few bits as possible.The other way, perceptual coding, exploits certain flaws in the human auditory system to encode a signal in such a way that it sounds the same to a human listener, even if it looks quite different on an oscilloscope. Perceptual coding is based on the science of psychoacoustics—how people perceive sound. MP3 is based on perceptual coding.The key property of perceptual coding is that some sounds can mask other sounds. Imagine you are broadcasting a live flute concert on a warm summer day. Then all of a sudden, a crew of workmen nearby turns on their jackhammers and start tearing up the street. No one can hear the flute any more. Its sounds have been masked by the jackhammers. For transmission purposes, it is now sufficient to encode just the frequency band used by the jackhammers because the listeners cannot hear the flute anyway. This is called frequency masking—the ability of a loud sound in one frequency band to hide a softer sound in another frequency band that would have been audible in the absence of the loud sound. In fact, even after the jackhammers stop, the flute will be inaudible for a short period of time because the ear turns down its gain when they start and it takes a finite time to turn it up again. This effect is called temporal masking.Answer the following questions within 50 words. Q1:Why is audio compression needed?Q2: What is mp3?Q3: What does the word psychoacoustics mean?Q4: What is the aim of waveform coding?Q5: What is perceptual coding?Passage TwoAlthough over 50 years old, the standard television signal is still one of the most common way to transmit an image. Figure 1 shows how the television signal appears on an oscilloscope. This is called composite video, meaning that there are vertical and horizontal synchronization (sync) pulses mixed with the actual picture information. These pulses are used in the television receiver to synchronize the vertical and horizontal deflection circuits to match the video being displayed. Each second of standard video contains 30 complete images, commonly called frames. A video engineer would say that each frame contains 525 lines, the television jargon for what programmers call rows. This number is a little deceptive because only 480 to 486 of these lines contain video information; the remaining 39 to 45 lines are reserved for sync pulses to keep the television's circuits synchronized with the video signal.Determine the following statement is true (T) or false (F):No. T/F StatementQ6: ( )The term composite video is an alias of standard television signal.Q7:( )There are more than one methods for video transmission mentioned in this passage.Q8:( )The composite video is a combination of frames, picture information and sync pulses.Q9:( )The number 30 frames/second is a little deceptive.Technical English Test for Electronic Information EngineeringDepartment____________ Class___________ Name____________SECTION 1Fill in the blanks with proper terms (30 minutes).SECTION 2Translate the following passages into Chinese (40 minutes).5.While traditional processors follow the V on Neumann architecture model, which assumes ashared single memory to be used for both program instructions and data, DSPs use the Harvard or modified Harvard architecture, which includes multiple program and data memories, along with multiple buses to access them. This arrangement means that much less waiting is required when instructions or numbers are fetched from memory.6.ITU recommended that all governments reserve spectrum at 2 GHz so devices could roamseamlessly from country to country. Later, it was recognized that 2 Mbps is not currently feasible for users who are too mobile (due to the difficulty of performing handoffs quickly enough) .7.Just like a conventional camera, a digital camera has a series of lenses that focus light to createan image of a scene. But instead of focusing this light onto a piece of film, it focuses it onto a semiconductor device that records light electronically. A microprocessor then breaks this electronic information down into digital data.8.Make sure the lens will handle the pictures you plan to take. If you don't have the right lens, itcan be hard to take the best pictures. For example, if very crisp detail is important in your pictures, you'll probably want a high optical zoom number. Be sure to try out the lens system ona camera before you purchase it. Digital cameras come with a huge variety of lenses, so be sureto shop around.SECTION 3Read the following passages and answer questions (30 minutes).Passage oneNature moves in the form of a sine wave, be it an ocean wave, earthquake, sonic boom, explosion, sound through air, or the natural frequency of a body in motion. Energy, vibrating particles and other invisible forces pervade our physical universe. Even light–part particle, part wave–has a fundamental frequency, which can be observed as color. Sensors can convert these forces into electrical signals that you can observe and study with an oscilloscope. Oscilloscopes enable scientists, engineers, technicians, educators and others to “see” ev ents that change over time.Oscilloscopes are indispensable tools for anyone designing, manufacturing or repairing electronic equipment. In today’s fast-paced world, engineers need the best tools available to solve their measurement challenges quickly and accurately. As the eyes of the engineer, oscilloscopes are the key to meeting today’s demanding measurement challenges.The usefulness of an oscilloscope is not limited to the world of electronics. With the proper transducer, an oscilloscope can measure all kinds of phenomena. A transducer is a device that creates an electrical signal in response to physical stimuli, such as sound, mechanical stress, pressure, light, or heat. A microphone is a transducer that converts sound into an electrical signal.Oscilloscopes are used by everyone from physicists to television repair technicians. An automotive engineer uses an oscilloscope to measure engine vibrations. A medical researcher uses an oscilloscope to measure brain waves. The possibilities are endless.Answer the following questions within 50 words.Q1: Are oscilloscopes signals sources? Why not?Q2: Does the word “demanding” mean difficult or easy?Q3: How can an oscilloscope measure the temperature change over time? Q4: What function does a sensor or a transducer perform?Q5: Please give the reason why oscilloscopes are regarded as the eyes of engineers?Passage TwoAlthough over 50 years old, the standard television signal is still one of the most common way to transmit an image. Figure 1 shows how the television signal appears on an oscilloscope. This is called composite video, meaning that there are vertical and horizontal synchronization (sync) pulses mixed with the actual picture information. These pulses are used in the television receiver to synchronize the vertical and horizontal deflection circuits to match the video being displayed. Each second of standard video contains 30 complete images, commonly called frames. A video engineer would say that each frame contains 525 lines, the television jargon for what programmers call rows.

Data acquisition systems usually require _anti-aliasing low-pass filters__（抗混叠低通滤波器 ) as well as low-pass noise filters in their preceding __signal conditioning_ ( 信号调治 )stages. System power supplies often use band-rejection filters to suppress the 60-Hz frequency and high frequency transients. In addition, there are filters that do not filter_ ( 滤除 )any frequencies of a complex input signal, but just add a ___linear phase shift__ (线性相移 )to each frequency component，thus contributing a constant __time delay__（时延） .These are called ___all-pass filter__ 全(通滤波器 ).At high frequencies (>1 MHz), all of these filters usually consist __of_ passive components __such as__ inductors (L), resistors (R), and capacitors(C). They are then __called______ LRC filters. In the low frequency range (1 Hz to 1 MHz), however, the inductor value becomes very large and the inductor itself gets quite bulky,___making__ economical production difficult. In these _cases_____, _active filters_(有源滤波器) becomes important. Active filters are circuits that use _operational amplifier__ ( 运算放大器) as the active device ___in__ combination with some resistors and capacitors to provide an LRC-like filter performance at low frequency.四 . 翻译（每题 5 分共 40 分）1.As in the first- order case, the second-order low-pass transfer function tends to zero as frequency tends to infinity.当频次趋近于无量时，二阶低通滤波器的传输函数趋近于零（和一阶低通滤波器的传输函数同样）。

电子信息工程专业英语教程_第5版 题库
《电子信息工程专业英语教程(第5版)》题库Section A 术语互译 (1)Section B 段落翻译 (5)Section C阅读理解素材 (12)C.1 History of Tablets (12)C.2 A Brief History of satellite communication (13)C.3 Smartphones (14)C.4 Analog, Digital and HDTV (14)C.5 SoC (15)Section A 术语互译Section B 段落翻译Section C阅读理解素材C.1 History of TabletsThe idea of the tablet computer isn't new. Back in 1968, a computer scientist named Alan Kay proposed that with advances in flat-panel display technology, user interfaces, miniaturization of computer components and some experimental work in WiFi technology, you could develop an all-in-one computing device. He developed the idea further, suggesting that such a device would be perfect as an educational tool for schoolchildren. In 1972, he published a paper about the device and called it the Dynabook.The sketches of the Dynabook show a device very similar to the tablet computers we have today, with a couple of exceptions. The Dynabook had both a screen and a keyboard all on the same plane. But Key's vision went even further. He predicted that with the right touch-screen technology, you could do away with the physical keyboard and display a virtual keyboard in any configuration on the screen itself.Key was ahead of his time. It would take nearly four decades before a tablet similar to the one he imagined took the public by storm. But that doesn't mean there were no tablet computers on the market between the Dynabook concept and Apple's famed iPad.One early tablet was the GRiDPad. First produced in 1989, the GRiDPad included a monochromatic capacitance touch screen and a wired stylus. It weighed just under 5 pounds (2.26 kilograms). Compared to today's tablets, the GRiDPad was bulky and heavy, with a short battery life of only three hours. The man behind the GRiDPad was Jeff Hawkins, who later founded Palm.Other pen-based tablet computers followed but none received much support from the public. Apple first entered the tablet battlefield with the Newton, a device that's received equal amounts of love and ridicule over the years. Much of the criticism for the Newton focuses on its handwriting-recognition software.It really wasn't until Steve Jobs revealed the first iPad to an eager crowd that tablet computers became a viable consumer product. Today, companies like Apple, Google, Microsoft and HP are trying to predict consumer needs while designing the next generation of tablet devices.C.2 A Brief History of satellite communicationIn an article in Wireless World in 1945, Arthur C. Clarke proposed the idea of placing satellites in geostationary orbit around Earth such that three equally spaced satellites could provide worldwide coverage. However, it was not until 1957 that the Soviet Union launched the first satellite Sputnik 1, which was followed in early 1958 by the U.S. Army’s Explorer 1. Both Sputnik and Explorer transmitted telemetry information.The first communications satellite, the Signal Communicating Orbit Repeater Experiment (SCORE), was launched in 1958 by the U.S. Air Force. SCORE was a delayed-repeater satellite, which received signals from Earth at 150 MHz and stored them on tape for later retransmission. A further experimental communication satellite, Echo 1, was launched on August 12, 1960 and placed into inclined orbit at about 1500 km above Earth. Echo 1 was an aluminized plastic balloon with a diameter of 30 m and a weight of 75.3 kg. Echo 1 successfully demonstrated the first two-way voice communications by satellite.On October 4, 1960, the U.S. Department of Defense launched Courier into an elliptical orbit between 956 and 1240 km, with a period of 107 min. Although Courier lasted only 17 days, it was used for real-time voice, data, and facsimile transmission. The satellite also had five tape recorders onboard; four were used for delayed repetition of digital information, and the other for delayed repetition of analog messages.Direct-repeated satellite transmission began with the launch of Telstar I on July 10, 1962. Telstar I was an 87-cm, 80-kg sphere placed in low-Earth orbit between 960 and 6140 km, with an orbital period of 158 min. Telstar I was the first satellite to be able to transmit and receive simultaneously and was used for experimental telephone, image, and television transmission. However, on February 21, 1963, Telstar I suffered damage caused by the newly discovered Van Allen belts.Telstar II was made more radiation resistant and was launched on May 7, 1963. Telstar II was a straight repeater with a 6.5-GHz uplink and a 4.1-GHz downlink. The satellite power amplifier used a specially developed 2-W traveling wave tube. Along with its other capabilities, the broadband amplifier was able to relay color TV transmissions. The first successful trans-Atlantic transmission of video was accomplished with Telstar II , which also incorporated radiation measurements and experiments that exposed semiconductor components to space radiation.The first satellites placed in geostationary orbit were the synchronous communication (SYNCOM ) satellites launched by NASA in 1963. SYNCOM I failed on injection into orbit. However, SYNCOM II was successfully launched on July 26, 1964 and provided telephone, teletype, and facsimile transmission. SYNCOM III was launched on August 19, 1964 and transmitted TV pictures from the Tokyo Olympics. The International Telecommunications by Satellite (INTELSAT) consortium was founded in July 1964 with the charter to design, construct, establish, and maintain the operation of a global commercial communications system on a nondiscriminatory basis. The INTELSAT network started with the launch on April 6, 1965, of INTELSAT I, also called Early Bird. On June 28, 1965, INTELSAT I began providing 240 commercial international telephone channels as well as TV transmission between the United States and Europe.In 1979, INMARSAT established a third global system. In 1995, the INMARSAT name was changed to the International Mobile Satellite Organization to reflect the fact that the organization had evolved to become the only provider of global mobile satellite communications at sea, in the air, and on the land.Early telecommunication satellites were mainly used for long-distance continental and intercontinental broadband, narrowband, and TV transmission. With the advent of broadband optical fiber transmission, satellite services shifted focus to TV distribution, and to point-to-multipoint and very small aperture terminal (VSAT) applications. Satellite transmission is currently undergoing further significant growth with the introduction of mobile satellite systems for personal communications and fixed satellite systems for broadband data transmission.C.3 SmartphonesThink of a daily task, any daily task, and it's likely there's a specialized, pocket-sized device designed to help you accomplish it. You can get a separate, tiny and powerful machine to make phone calls, keep your calendar and address book, entertain you, play your music, give directions, take pictures, check your e-mail, and do countless other things. But how many pockets do you have? Handheld devices become as clunky as a room-sized supercomputer when you have to carry four of them around with you every day.A smartphone is one device that can take care of all of your handheld computing and communication needs in a single, small package. It's not so much a distinct class of products as it is a different set of standards for cell phones to live up to.Unlike many traditional cell phones, smartphones allow individual users to install, configure and run applications of their choosing. A smartphone offers the ability to conform the device to your particular way of doing things. Most standard cell-phone software offers only limited choices for re-configuration, forcing you to adapt to the way it's set up. On a standard phone, whether or not you like the built-in calendar application, you are stuck with it except for a few minor tweaks. If that phone were a smartphone, you could install any compatible calendar application you like.Here's a list of some of the things smartphones can do:•Send and receive mobile phone calls•Personal Information Management (PIM) including notes, calendar and to-do list•Communication with laptop or desktop computers•Data synchronization with applications like Microsoft Outlook•E-mail•Instant messaging•Applications such as word processing programs or video games•Play audio and video files in some standard formatsC.4 Analog, Digital and HDTVFor years, watching TV has involved analog signals and cathode ray tube (CRT) sets. The signal is made of continually varying radio waves that the TV translates into a picture and sound. An analog signal can reach a person's TV over the air, through a cable or via satellite. Digital signals, like the ones from DVD players, are converted to analog when played on traditional TVs.This system has worked pretty well for a long time, but it has some limitations:•Conventional CRT sets display around 480 visible lines of pixels. Broadcasters have been sending signals that work well with this resolution for years, and they can't fit enough resolution to fill a huge television into the analog signal.•Analog pictures are interlaced - a CRT's electron gun paints only half the lines for each pass down the screen. On some TVs, interlacing makes the picture flicker.•Converting video to analog format lowers its quality.United States broadcasting is currently changing to digital television (DTV). A digital signal transmits the information for video and sound as ones and zeros instead of as a wave. For over-the-air broadcasting, DTV will generally use the UHF portion of the radio spectrum with a 6 MHz bandwidth, just like analog TV signals do.DTV has several advantages:•The picture, even when displayed on a small TV, is better quality.• A digital signal can support a higher resolution, so the picture will still look good when shown on a larger TV screen.•The video can be progressive rather than interlaced - the screen shows the entire picture for every frame instead of every other line of pixels.•TV stations can broadcast several signals using the same bandwidth. This is called multicasting.•If broadcasters choose to, they can include interactive content or additional information with the DTV signal.•It can support high-definition (HDTV) broadcasts.DTV also has one really big disadvantage: Analog TVs can't decode and display digital signals. When analog broadcasting ends, you'll only be able to watch TV on your trusty old set if you have cable or satellite service transmitting analog signals or if you have a set-top digital converter.C.5 SoCThe semiconductor industry has continued to make impressive improvements in the achievable density of very large-scale integrated (VLSI) circuits. In order to keep pace with the levels of integration available, design engineers have developed new methodologies and techniques to manage the increased complexity inherent in these large chips. One such emerging methodology is system-on-chip (SoC) design, wherein predesigned and pre-verified blocks often called intellectual property (IP) blocks, IP cores, or virtual components are obtained from internal sources, or third parties, and combined on a single chip.These reusable IP cores may include embedded processors, memory blocks, interface blocks, analog blocks, and components that handle application specific processing functions. Corresponding software components are also provided in a reusable form and may include real-time operating systems and kernels, library functions, and device drivers.Large productivity gains can be achieved using this SoC/IP approach. In fact, rather than implementing each of these components separately, the role of the SoC designer is to integrate them onto a chip to implement complex functions in a relatively short amount of time.The integration process involves connecting the IP blocks to the communication network, implementing design-for-test (DFT) techniques and using methodologies to verify and validate the overall system-level design. Even larger productivity gains are possible if the system is architected as a platform in such as way that derivative designs can be generated quickly.In the past, the concept of SoC simply implied higher and higher levels of integration. That is, it was viewed as migrating a multichip system-on-board (SoB) to a single chip containing digital logic, memory, analog/mixed signal, and RF blocks. The primary drivers for this direction were the reduction of power, smaller form factor, and lower overall cost. It is important to recognize that integrating more and more functionality on a chip has always existed as a trend by virtue of Moore’s Law, which predicts that the number of transistors on a chip will double every 18-24 months. The challenge is to increase designer productivity to keep pace with Moore’s Law. Therefore, today’s notion of SoC is defined in terms of overall productivity gains through reusable design and integration of components.。

Translate the following passages into Chinese or English 。
Unit 2
1、It is extremely hard to definite dynamic range （DR ）for an op amp ，so let is start with a digital-to-analog converter （DAC ） where DR is define as the ratio of the Maximum output voltage to the smallest output voltage the DAC can produce
译文：由于很难定义运算放大器的“动态范围”（DR ），因此先给“数模转换器”（DAC ）的动态范围下定义。
DAC 的动态范围就是其最大输出电压和最小输出电压之比。
2、The same definition of DR can be used for an op amp ，and the maximum output voltage swing equals OUTMAX V 。
This output voltage swing is defined as the maximum output voltage the op amp can achieve （OH V ） minus the minimum output voltage the op amp can achieve （OL V ）。
OH V and OL V are easily obtainable from an op amp IC data sheet 。
译文：这个“动态范围”的定义也可用于运算放大器，其最大输出电压摆幅为OUTMAX V 。
输出电压摆幅定义为运算放大器能达到的最大输出电压（OH V ）减去最小输出电压（OL V ）。
从运放集成电路数据手册中，可以很容易获得OH V 和OL V 。
3、电压和水有相似之处——当其供应量很少时，人们才会认识到其价值。
低电压系统（此处是指低于5V 的单电源供电）让我们认识到电压的价值。
译文：In one respect ，voltage is like water ：you don't appreciate its value until your supply runs low ；Low —voltage systems ，defined here as a single power supply less than 5V ，teach us to appreciate voltage 。
4、在电子技术个领域中，欧姆定律都是基本定律。
欧姆定律可表述为R I V ∙=。
欧姆定律可应用于单个器件、一组器件或一个完整电路。
当已知流过电路中各部分的电流时，其电压降可由电阻和电流的乘积获得。
译文：Ohm’s law is stated as R I V ∙= ,and it is fundamental to all electronics 。
Ohm’s law can be applied to a single component,to any group
of component,or to a complete circuit。
When the current flowing through any portion of a circuit is know ,the voltage dropped across that portion of the circuit is obtained by multiplying the current times the resistance。
5、电路就是无源器件和有源器件的组合。
器件按照特定方式排列，以完成期望的功能。
器件的排列就形成了一个电路，或叫做电路结构。
模拟电路设计就是开发各种电路结构。
译文:Circuits are a mix of passive and active components.The components are arranged in a manner that enables them to perform some desired function.The resulting arrangement of components is called a circuit or sometimes a circuit configuration.The art portion of analog design is developing the circuit configuration.。
