电子信息专业英语课文翻译1. Chapter 1 Introduction to Electronic Technology电子技术简介1.1. Lesson 1 Development of Electronics 电子技术发展史电子技术的历史是一个关于二十世纪的故事,电子学的三个关键元件是真空管、晶体管和集成电路。
真空管也叫做电子管,它是一个密封的玻璃管,在它里面,电子在有真空隔离的电极之间流动。
在20(19×)世纪早期发明了真空管,随着真空管的发明,放大和传输电能成为可能。
电子管的第一应用在于无线电通信。
在第二次世界大战之前,随着越来越多的专门真空管被制造出来用于各种用途,通信技术从而能得到了巨大的进步。
在20世纪20年代时,无线电广播呈天文数字地增长并且成为家庭娱乐的主要来源。
电视机是在1927年发明,并且最终得到了广泛的应用。
电视机作为一种电子设备,其发展得益于在二次世界大战期间雷达上的许多进步。
雷达利用无线电微波回声来测量一个物体的距离和方向,被用于检测飞机和船只。
世界大战之后,电子管被用于开发第一台计算机,但是因为电子元件的尺寸,所以这些计算机是不切实际的。
在1947年,来自贝尔实验室的一组工程师们发明了晶体管,因为发明了晶体管,他们获得了诺贝尔奖。
晶体管的功能类似于真空管,但与真空管相比,它体积小、重量轻、消耗功率低、更加可靠和制造成本低。
在几乎所有的电子设备中晶体管取代了真空管。
在20世纪 50年代时,美国德州仪器公司发展出第一个集成电路。
第一个集成电路仅包含了几个晶体管,在随后的20世纪70年代中期,出现了大规模集成电路和超大规模集成电路。
超大规模集成电路技术允许我们在一个单芯片中构建一个包含有成千上万晶体管的系统。
摄像机、手提电话和个人电脑仅仅是集成电路使之成为可能的一些设备实例。
1.2. Lesson 2 Singapore Polytechnic 新加坡理工学院新加坡理工学院,是新加坡同类学校中的第一家教育机构,创立于1954年,学院着重培养和训练技术人员和专业人员,从而支持新加坡的工业和经济的发展。

电子信息类英文资料加翻译Sequential Logic Test1.1 INTRODUCTIONThe previous chapter examined methods for creating sensitized paths in combina-tional logic extending from stuck-at faults on logic gates to observable outputs. Wenow attempt to create tests for sequential circuits where the outputs are a functionnot just of present inputs but of past inputs as well. The objective will be the same:to create a sensitized path from the point where a fault occurs to an observable out-put. However, there are new factors that must be taken into consideration. A sensi-tized path must now be propagated not only through logic operators, but also through an entirely new dimension—time. The time dimension may be discrete, asin synchronous logic, or it may be continuous, as in asynchronous logic.The time dimension was ignored when creating tests for faults in combinationallogic.It was implicitlyassu med that the output response would stabilize before being measured with test equipment, and it was generally assumed that each test pat-tern was independent of its predecessors. As will be seen, the effects of time cannotbe ignored, because this added dimension greatly influences the results of test pat-tern generation and can complicate, by orders of magnitude, the problem of creatingtests. Assumptions about circuit behavior must be carefully analyzed to determinethe circumstances under which they prevail.1.2 TEST PROBLEMS CAUSED BY SEQUENTIAL LOGIC Two factors complicate the task of creating tests for sequential logic: memory andcircuit delay. In sequential circuits the signals must not only be logically correct, butmust also occur in the correct time sequence relative to other signals. The test prob-lem is further complicated by the fact that aberrant behavior can occur in sequentialcircuits when individual discrete components are all fault-free and conform to theirmanufacturer’s specifications. We first consider problems caused by the presence ofmemory, and then we examine the effects of circuit delay on the test generation problem.1.2.1 The Effects of MemoryIn the first chapter it was pointed out that, for combinational circuits, it was possible(but not necessarily reasonable) to create a complete test for logic faults by applyingall possible binary combinations to the inputs of a circuit. That, as we shall see, is not true for circuits with memory. They may not only require more than 2 tests, butare also sensitive to the order in which stimuli are applied.Test Vector Ordering The effects of memory can be seen from analysis of thecross-coupled NAND latch [cf. Figure 2.3(b)]. Four faults will be considered, thesebeing the input SA1 faults on each of the two NAND gates (numbering is from topto bottom in the diagram). All four possible binary combinations are applied to theinputs in ascending order—that is, in the sequence (Set, Reset) = {(0,0), (0,1), (1,0),(1,1)}. We get the following response for the fault-free circuit (FF) and the circuit corresponding to each of the four input SA1 faults.InputOutputSet Reset FF 1 2 340 0 1 0 1 110 1 1 0 1 111 0 0 0 0 011 1 0 0 0 11In this table, fault number 2 responds to the sequence of input vectors with an outputresponse that exactly matches the fault-free circuit response. Clearly, this sequenceof inputs will not distinguish between the fault-free circuit and a circuit with input 2SA1.The sequence is now applied in the exact opposite order. We get:Input OutputSet Reset FF 1 2 341 1 ? ? 01 ?1 0 0 0 00 ?0 1 1 0 1 110 0 1 0 1 11The Indeterminate Value When the four input combinations are applied in reverse order, question marks appear in some table positions. What is their signifi-cance? To answer this question, we take note of a situation that did not exist whendealing only with combinational logic; the cross-coupled NAND latch has memory.By virtue of feedback present in the circuit, it is able to remember the value of a sig-nal that was applied to the set input even after that signal is removed.Because of the feedback, neither the Set nor the Reset line need be held low anylonger than necessary to effectively latch the circuit. However, when power is firstapplied to the circuit, it is not known what value is contained in the latch. How cancircuit behavior be simulated when it is not known what value is contained in its memory?In real circuits, memory elements such as latches and flip-flops have indetermi-nate values when power is first applied. The contents of these elements remain indeterminate until the latch or flip-flop is either set or reset to a known value. In asimulation model this condition is imitated by initializing circuit elements to the indeterminate X state. Then, as seen in Chapter 2, some signal values can drive a logic element to a known state despite the presence of indeterminate values on other inputs. For example, the AND gate in Figure 2.1(c) responds with a 0 when any single input receives a 0, regardless of what values are present on other inputs. However, if a 1 is applied while all other inputs are at X, the output remains at X.Returning to the latch, the first sequence began by applying 0s to both inputs,while the second sequence began by applying 1s to both inputs. In both cases the internal nets were initially indeterminate. The 0s in the first sequence were able todrive the latch to a known state, making it possible to immediately distinguishbetween correct and incorrect response. When applying the patterns in reverse order,it took longer to drive the latch into a state where good circuit response could be dis-tinguished from faulty circuit response. As a result, only one of the four faults is detected, namely, fault 1. Circuits with faults 2 and 3 agree with the good circuit response in all instances where the good circuit has a known response. On the firstpattern the good circuit respons is indeterminate and the circuit with fault 2responds with a 0. The circuit with fault 3 responds with a 1. Since it is not knownwhat value to expect from the good circuit, there is no way to decide whether the faulted circuits are responding correctly.Faulted circuit 4 presents an additional complication. Its response is indetermi-nate for both the first and second patterns. However, because the good circuit has aknown response to pattern 2, we do know what to look for in the good circuit, namely, the value 0. Therefore, if a NAND latch is being tested with the second setof stimuli, and it is faulted with input 4 SA1, it might come up initially with a 0 onits output when power is applied to the circuit, in which case the faul is not detected, or it could come up with a 1, in which case the fault will be detected. Oscillations Another complication resulting from the presence of memory is oscillations. Suppose that we first apply the test vector (0,0) to the cross-coupled NAND latch. Both NAND gates respond with a logic 1 on their outputs. We then apply the combination (1,1) to the inputs. Now there are 1s on both inputs to each ofthe two NAND gates—but not for long. The NAND gates transform these 1s into 0son the outputs. The 0s then show up on the NAND inputs and cause the NAND out-puts to go to 1s. The cycle is repetitive; the latch is oscillating. We do not know whatvalue to expect on the NAND gate outputs; the latch may continue to oscillate until adifferent stimulus is applied to the inputs or the oscillations may eventually subsideIf the oscillations do subside, there is no practical way to predict, from a logic description of the circuit, the final state into which the latch settles. Therefore, theNAND outputs are set to the indeterminate X.Probable Detected Faults When we analyzed the effectivenes of binary sequences applied to the NAND latch in descending order, we could not claimwithcertainty that stuck-at fault number 4 would be detected. Fortunately, that fault isdetected when the vectors are applied in ascending order. In other circuits the ambi-guity remains. In Figure 2.4(b) the Data input is complemented and both true andcomplement values are applied to the latch. Barring the presence of a fault, the latchwill not oscillate. However, when attempting to create a test for the circuit, we encounter another problem. If the Enable signal is SA1, the output of the inverterdriven by Enable is permanently at 0 and the NAND gates driven by the inverter arepermanently in a 1 state; hence the faulted latch cannot be initialized to a known state. Indeterminate states were set on the latch nodes prior to the start of test patterngeneration and the states remain indeterminate for the faulted circuit. If power is applied to the fault-free and faulted latches, the circuits may just happen to come upin the same state.The problem just described is inherent in any finite-state machine (FSM). TheFSM is characterized by a set of states Q = {q , q , ..., q }, a set of input stimuli1 2 sI = {i , i , ..., i }, another set Y = {y , y , ..., y } of output responses, and a pair of1 2 n 1 2 m Mappings M : Q × I → QZ : Q × I → YThese mappings define the next state transition and the output behav ior in responseto any particular input stimulus. These mappings assume knowledge of the currentstate of the FSM at the time the stimulus is applied. When the initial stimulus is applied, that state is unknown unless some independent means such as a reset existsfor driving the FSM into a known state.In general, if there is no independent means for initializing an FSM, and if theClock or Enable input is faulty, then it is not possible to apply just a single stimu-lus to the FSM and detect the presence of that fault. One approach used in industryis to mark a fault as a probable detect if the fault-free circuit drives an output pinto a known logic state and the fault causes that same pin to assume an unknown state.The industry is not in complete agreement concerning the classification of proba-ble detected faults. While some test engineers maintain that such a fault is likely toeventually become detected, others argue that it should remain classified as undetec-ted, and still others prefer to view it as a probable detect. If the probable detectedfault is marked as detected, then there is a concern that an ATPG may be designed toignore the fault and not try to create a test for it in those situations where a test exists.The Initialization Problem Consider the circuit of Figure 5.1. During simula- tion, circuit operation begins with the D flip-flop in an unknown state. In normal operation, when the input combination A = B = C = 0 is applied and the flip-flop isclocked, the Q output switches to 0. The flip-flop can then be clocked a second timeto obtain a test for the lower input of gate 3 SA1. If it is SA1, the expected value isQ = 1; and if it is fault-free, the expected value is Q = 0.Unfortunately, the test has a serious flaw! If the lower input to gate 3 is SA1, theoutput of the flip-flop at the end of the first clock period is indeterminate because thevalue at the middle input to gate 3 is initially indeterminate. It is driven by the flip-flop that has an indeterminate value. After a second clock pulse the value at Q willremain at X; hence it may agree with the good circuit response despite the presenceof the fault. The fallacy lies in assuming correct circuit behavior when setting up theflip-flop for the test. We depended upon correct behavior of the very net that we areattempting to test when setting up a test to detect a fault on that net.To correctly establish a test, it is necessary to assume an indeterminate value fromthe flip-flop. Then, from the D-algorithm, we know that the flip-flop must be driveninto the 0 state, without depending on the input to gate 3 that is driven by the flip-flop. The flip-flop v alue can then be used in conjunction with the inputs to test for the SA1 on the lower input of gate 3. In this instance, we can set A = C = 0, B = 1. Then a 1 can be clocked into the flip-flop from gate 2. This produces a 0 on the out-put of the flip-flop which can then be used with the assignment A = B = 0 to clock a0 into the flip-flop. Now, with Q = 0 and A = B = C = 0, another clock causes D to appear on the output of the flip-flop.Notice that input C was used, but it was used to set up gate 2. If input C werefaulted in such a way as to affect both gates 2 and 3, then it could not have been usedto set up the test.1.2 .2 Timing ConsiderationsUntil now we have assumed that erroneous behavior on circuit outputs was the result of logic faults. Those faults generall result from actual physical defects such as opens or shorts, or incorrect fabrication such as an incorrect connection or a wrong component. Unfortunately, this assumption, while convenient, is an oversimplifica- tion. An error may indeed be a result of one or more logic faults, but it may also be the case that an error occurs and none of the above situations exists.Defects exist that can prevent an element from behaving in accordance with its specifications. Faults that affect the performance of a circuit are referred to as para- metric faults, in contrast to the logic faults that have been considered up to this point. Parametric faults can affect voltage and current levels, and they can affect gain and switching speed of a circuit. Parametric faults in components can result from improper fabrication or from degradation as a consequence of a normal aging process. Environmental conditions such as temperature extremes, humidity, or mechanical vibration can accelerate the degradation process.Design oversights canproduce symptoms similar to parametric faults. Design problems include failure to take into account wire lengths, loading of devices, inad- equate decoupling, and failure to consider worst-case conditions such as maximum or minimum voltages or temperatures over which a device may be required to oper- ate. It is possible that none of these factors may cause an error in a particular design in a well-controlled environment, and yet any of these factors can destabilize a cir- cuit that is operating under adverse conditions. Relative timing between signal paths or the ability of the circuit to drive other circuits could be affected.Intermit tenterrors are particularly insidious because of their rather elusive nature, appearing only under particular combinations of circumstances. Forexam-ple, a logic board may be designed for nominal signal delay for each component as asafety margin. Statistically, the delays should seldom accumulate so as to exceed acritical threshold. However, as with any statistical expectation, there will occasion-ally be a circuit that does exceed the maximum permissible value. Worse still, it maywork well at nominal voltages and /or temperatures and fail only when voltages and/or temperatures stray from their nominal value. A new board substituted for the orig-inal board may be closer to tolerance and work well under the degraded voltage and or temperature conditions. The original board may then, when checked at a depot or a board tester under ideal operating conditions, test satisfactorily.Consider the effects of timing variations on the delay flip-flop of Figure 2.7. Cor-rect operation of the flip-flop requires that the designer observe minimal setup andhold times. If propagation delay along a signal path to the Data input of the flip-flopis greater than estimated by the designer, or if parametric faults exist, then the setuptime require ment relative to the clock may not be satisfied, so the clock attempts tolatch the signal while it is still changing. Problems can also occur if a signal arrivestoo soon. The hold time requirement will be violated if a new signal value arrives atthe d ata input before the intended value is latched up in the flip-flop. This can hap-pen if one register directly feeds another without any intervening logic.That logic or parametric faults can cause erroneous operation in a circuit is easyto understand, but digital test problems are further compounded by the fact thaterrors can occur during operation of a device when it components behave as intended. Elements used in the fabrication of digital logic circuits contain delay.Ironically, although technologists constantly try to create faster circuits and reducedelay, sequential logic circuits cannot function without delay; circuits depend both on correct logic operation of circuit components and on correct relativetiming ofsignals passing through the circuit. This delay must be taken into account when designing and testing circuits.Suppose the inverter driven by the Data input in the gated latch circuit ofFigure 2.4(b) has a delay of n nanoseconds. If the Data input makes a 0-to-1 transi-tion followed by a 0-to-1 transition on the Enable approximately n nanoseconds later, the two cross-coupled NAND gates see an input of (0,0) for about n nanosec-onds followed by an input of (1,1). This produces unpredictable results, as we haveseen before. The problem is caused by the delay in the inverter. A solution to this problem is to put a buffer in the noninverting signal path so the Data and Data sig-nals reach the NANDs at about the same time.In each of the two circuits just cited, the delay flip-flop and the latch, a race exists. A race is a condition wherein two or more signals are changing simulta-neously in a circuit. The race may be caused by multiple simultaneous input signalchanges, or it may be the result of a single signal change that follows two or more paths from a fanout point. Note that any time we have a latch or flip-flop we have arace condition, since these devices will always have at least one element whose sig-nal both goes outside the device and feeds back to an input of the latch or flip-flop.Races may or may not affect the behavior of a circuit. A critical race exists if the behavior of a circuit depends on the outcome of the race. Such races can produce unanticipated and unwanted results.Hazards can also cause sequential circuits to behave in ways that were not sidered. Like timing problems, hazards can be extremely difficult to diagnose because their effect on a circuit may depend on other factors, such as marginal volt-ages or an operating temperature that is within specification but borderline. Underoptimal conditions, a glitch caused by a hazard may not contain enough energy tocause a latch to switch state; but under the influence of marginal operating condi-tions, this glitch may have sufficient energy to cause a latch of flip-flop to switch states.顺序逻辑测试1.1介绍前一章检查方法在结合创建敏化的路径——从固定逻辑,传统逻辑,扩展逻辑门上的断层,可观察到的输出。

Unit 1 Current, Voltage and Resistance
We shall define voltage “across” an element as the work
done in moving a unit charge (+1C) through the element from one terminal to the other. The term voltage (represented by the letter symbol U) is commonly used to indicate both a potential difference and an electromotive force. The unit in which voltage is measured is the volt(V). One volt is defined as that magnitude of electromotive force required cause a current of one ampere to pass through a conductor having a resistance of one ohm. Besides the volt, smaller or larger magnitude of voltage are expressed in millivolts(mV), microvolts(μV) or kilovolts(kV).

P192.6 MobilityGSM is a cellular telephone system that supports mobility over a large area. Unlike cordless telephone systems, it provides location,roaming, and hand-over. GSM是移动电话系统,在一个大面积内支持流动性。
与无线电话系统相比,它还能提供定,漫游和区域切换等。
2.6.1 Location AreaThe ability to locate a user is not supported in first-generation cellular systems. This means that when a mobile is called, the network has to broadcast the notification of this call in all the radio coverage. In GSM, however, location areas (LAs), which are groups of cells, are defined by the operator. The system is able to identify the LA in which the subscriber is located. This way, when a user receives a call, the notification (or paging) is only transmitted in this area. This is far more efficient, since the physical resource use is limited.第一代蜂窝系统不能够准确找到用户所在位臵。
这意味着,当有一个电话被叫时,网络得在无线信号覆盖的整个区域内发出该电话的通知。
然而在GSM网络中,位置区域(LAs)即若干个小区组成的区群,由经营者指定。
该系统能够确定用户所在的位置区域。
这样,当用户收到一个电话,通知(或传呼)只在这个区域内转交。
这是更为有效,尽管物理资源的使用是有限的。
Roaming In particular, the GSM system has the capability of international roaming, or the ability to make and receive phone calls to and from other nations as if one has never left home. This is possible because bilateral agreements have been signed between the different operators, to allow GSM mobile clients to take advantage of GSM services with the same subscription when traveling to different countries, as if they has a subscription to the local network. To allow this, the SIM cark contains a list of the networks with which a roaming agreement exists. When a user is ‘roaming’ to a foreign country, the mobile phone automatically starts a search for a network stipulated on the SIM card list. The choice of a network is performed automatically, and if more than one network is given in the list, the choice is based on the order in which the operators appear. This order can be changed by the user. The home PLMN is the network in which the user has subscribed, while the visited PLMN often refers to the PLMN in which the user is roaming. When a user receives a call on a visited PLMN, the transfer of the call from the home PLMN to the visited PLAN is charged to the called user by his operator.特别是,GSM系统支持国际漫游,能够在其它国家发起或接收呼叫,就像在自己家里一样。
这是可能的,因为不同运营商之间的双边协定已经签署了,允许GSM移动的客户在不同的国家旅行时能够利用GSM服务,就像它们已经订购了本地网络一样。
为了实现这一点,SIM卡中包含了一个网络清单,其中包含有漫游协议。
当用户漫游到国外,手机自动开始搜索SIM卡清单上规定的网络。
选择网络是自动执行的,如果列表中的网络有多个,则根据运营商规定的顺序进行选择。
选择顺序可以被用户修改。
主PLMN是指用户已在此认购的网络,而通常指的是用户漫游到的网络。
当用户在访问PLMN收到一个电话,从主PLMN到访问PLMN的转移呼叫由他的运营商记入被叫用户。
2.6.3 HandoverWhen the user is moving from one cell to the other during a cell, the radio link between BTS 1 and the MS can be replaced by another link, between BTS 2 and the MS. The continuity of the call can be performed in a seamless way for the user. This is called handover. Which respect to dual-band telephones, one interesting feature is called the dual-band handover. It allows the user in an area covered both by the GSM-900 and by the DCS-1800 frequency bands, for instance, to be ableto transfer automatically from one system to the other in the middle of a call. 2.6.3当用户正在从一个小区转入另一个小区,BTS1和用户之间的无线信号链接可转至。
BTS2和用户之间的无线信号链接。
通话的连续性可为用户提供一个无缝的连接。
这就是所谓的移交。
这方面的双频电话,一个有趣的特点是所谓的双频段切换。
它允许用户在一个覆盖了GSM-900和DCS-1800频带的区域内能够在一次通话中自动地从一个系统转移到另一个系统中。
2.7 Beacon ChannelFor each BTS of a GSM network, one frequency channel is used to broadcast general signaling information about this cell. This particular carrier frequency is called a beacon channel, and it is transmitted by the BTS with the maximum power used in the cell, so that every MS in the cell is able to receive it. 对于GSM网络中的每个基站,使用其中一个信道来承载该小区的主要信号。
这种特殊的载波频率被称为信标信道,它在整个小区中的功率最大,使小区中的每个用户能够收到它。
2.8 MS Idle ModeWhen it is not in communication, but still powered on, the MS is said to be in idle mode. This means that it is in a low consumption mode, but synchronized to the network and able to receive or initiate calls.2.8当用户处于开机状态但不在进行通信时,可视为待机模式。
这就是说,此时它处于低耗状态,但和网络同步,并能够接收或发起呼叫。
UNIT 14Immersive interactive technology is one of the modern DSP topics – it’s at the intersection of the traditionally separate areas of computer animation , computer vision , graphics ,speech and audio processing ,image and video processing , and communications.沉浸式的交互技术是现代的 DSP 课题之一 ---它的计算机动画、计算机视觉、图形、语音和音频处理、图像和视频处理和通讯的传统上不同区域的交叉点。
The topic of this special issue is immersive interactive technologies .It represents one of the “modern”topic in DSP and is at the intersection of the traditionally separate areas of computer animation,computer vision,graphics,speech and audio processing,image and video processing,and communications(not to mention psychology,physiology,kinesiology,and control).Such R&D topics act as a catalyst in bringing together researchers from outside the digital signal processing area,and this is clear by looking at the authors in this issue. Each article brings a different perspective to the discussion.这个特殊问题的主题是沉浸式交互技术.它代表了DSP的“现代”的主题之一,是在计算机动画,计算机视觉,图像,语音和音频处理,图像和视频处理的传统独立区域的交叉身临其境的互动技术和通信(更不用说心理学,生理学,运动学和控制)。
