A filter is a device that passes electric signals __at_ certain frequencies or frequency ranges __while_ preventing the passage of others.Filter circuits are used ___in____ a wide variety of applications. In the filed of telecommunication (在电信领域),band-pass filters are used in the audio frequency range (0kHz to 20kHz) for __modem and speech processing__ (调制解调器和语音处理).High-frequency band-pass filters(several hundred MHz) are used for ____channel selection_ (信道选择)in telephone central offices. 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_ (信号调理)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.当频率趋近于无穷时，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一样）。

At present, the state of most semiconductor device technology is such that the device design and process technology must be supplemented by screening and inspection procedures, if ultimate device reliability is to be obtained and controlled．2). The converter is essentially a highly over –sampling 1-bit ADC (the comparator) followed by digital filtering and decimation to realize the processing gain. The effective performance of the converter is greatly enhanced by the addition of circuitry to shape the quantization noise such that, instead of being uniformly spread throughout the 0 to fs/2 band, it is minimized in the band of interest.3). Although the individual integrated circuits might cost as little as 10 cents each, the cost of designing the printed circuit board for such a system and the cost of assembling the board are very significant and this design style is no longer cost-effective.4).

The electrically interconnected components that make up an IC are called integrated elements. If an integrated circuit includes only one type of components, suchas only diodes or resistors, it is said to be an assembly or set of components.The principle of integrated circuit elements lies in the following. A great number of “set” are produced simultaneously on a wafer. Each set contains all the components such as transistors, diodes, and resistor which are interconnected with short fine metallic stripes deposited on the wafer surface. They make up an functional block. Each ICs of components is a ready integrated circuit. All ICs are regularly distributed on the wafer surface.ICs can be classified by function into two: circuits to be applied in digital systems and those to be applied in linear systems. The digital ICs are employed mostly in computers, electronic counters, frequency synthesizers and digital instruments. And the analog, or linear ICs operate over a continuous range, and include such devices as operational amplifiers.The invention of IC is a great revolution in the electronic industry. Sharp size, weight reductions are possible with these techniques; and more importantly, high reliability, excellent functional performance, low cost and low power dissipation can be achieved.Questions for text:1.What types of elements may integrated circuits possibly include?2.Tell some advantages of using integrated circuits.(2)Pulse-Code ModulationPulse-Code Modulation (PCM) is the most basic form of digital pulse modulation. In pulse-code modulation, a message signal is represented by a sequence of coded pulses, which is accomplished by representing the signal in discrete form in both time and amplitude. The basic operations performed in the transmitter of PCM are sampling, quantizing, and encoding. The quantizing and encoding operations are usually performed in the same circuit, which is called analog-to-digital converter. The basic operations in the receiver are regeneration of impaired signals, decoding, and reconstruction of the train of quantized samples. In what follows, we describe the various operations that constitute a basic PCM system.Sampling. The incoming message signal is sampled with a train of narrow rectangular pulses.Quantization. The sampled version of the message signal is then quantized, thereby providing a new representation of the signal that is discrete in both time and amplitude.Encoding. Any plan for representing each of this discrete set of sample values as a group of particular binary numbers is called encoding.Regeneration. The most important feature of PCM systems lies in the ability to control the effects of distortion and noise produced by transmitting a PCM signal through a channel. This capability is accomplished by reconstructing the PCM signal by means of a chain of regenerative repeaters located考 生 信 息 栏系 专业 级 班级 姓名 学号 装 订 线sufficiently close spacing along the transmission route.Decoding. The decoding process involves generating a pulse, the amplitude ofwhich is the linear sum of all the pulses in the code word, with each pulse beingweighted by its place value (20,21,22,…,2R-1) in the code, where R is the number of bitsper sample.Filtering. The final operation in the receiver is to recover the message signal by passing the decoder output through a low-pass filter whose cutoff frequency is equal to the message bandwidth W. Questions for text: 1. What is “PCM” short for? 2. What are the basic operations performed in the transmitter of PCM? 3. What are the basic operations performed in the receiver of PCM? 七、将下列英文翻译成中文 （本题共12小题，每题3分，共36分） 1. 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. 2. The circuit designers are not generally interested in the internal components of an integrated circuit, but only in the performance of the unit as a whole. 3. A computer consists of an input/output (I/O) device, memory, a control section, and an arithmetic and logic unit (ALU), which is the computational element. 4. Because of ever more powerful computer systems and the experience of creative programmers, multimedia is truly changing the way people are using computers. 5. When a call between a mobile subscriber and an ordinary subscriber has been set up, the speech is transmitted on the radio path between the mobile station and a voice channel unit of the base station situated close to the mobile station. 6. At today’s level of development, the IC might comprise more than ten thousand separate electronic elements including elements of many different functions, such as diodes, transistors, capacitors and resistors. 7. Just as in the decimal system, every time we shift a symbol one place to the left, we multiply its value by the base 2. 8. Unlike many other threats, a computer virus can spread from program to program and from system to system, without direct human intervention(介入). 9. The fiber optic systems do not use a conventional power source and can be more easily used in hazardous(危险的)areas.10.A multimeter is a general-purpose meter capable of measuring DC and AC voltage, current,resistance, and in some cases, decibels(分贝).11.This is accomplished by using a process known as demodulation, which is the reverse of themodulation process.12.Once the message is entirely received, the message processor examines its header, and accordinglydecides on the next outgoing channel on which to transmit it.八、将下列中文翻译成英文（本题共2小题，每题2分，共4分）1.网络的优势在于它能够方便快捷地传递消息。
