第一课1.将下述句子译成英文。
(1) An analog information source produces messages that are defined on a continuum, whilea digital information source produces a finite set of possible messages.(2) The beacon-fire tower in ancient China was a communications system.(3) Show that the entropy is a maximum when the probability of sending a binary 1 is equalto the probability of sending a binary 0 .(4) Information capacity is a measure of how much information can be transferred through acommunications system in a given period of time .(5) The wider the bandwidth and the longer the time of transmission, the more informationcan be conveyed through the system .2.Answer the following questions :(1) Samuel Morse developed the first electronic communications system in 1837 .(2) Y es.(3) The vacuum-tube triode .(4) Hartley’s law simply states that the wider the bandwidth and the longer the transmissiontime, the more information that can be conveyed through the system . The Shannon’s formula is I=B log2(1+S/N) , where I=information capacity(bps), B=bandwidth(Hz), S/N=signal-to-noise power ratio(unitless) .(5) (a) VLF, (b) MF, (c) SHF第二章信息源1.根据课文回答下列问题。

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). Rather than just matching the abilities of the human ear, these systems are designed to exceed the limits of hearing. It's the only way to be sure that the reprod uced music is pristine.5). In the case that the object types in a video sequence belong to known object classes, knowledge-based coding can be employed, which uses a wireframe specially designed to describe the recognized object type. Several approaches have been developed to code human heads using predefined wireframes. Using a predefined wireframe increases coding efficiency because it is adapted to the shape of the object. Sometimes. this technique is also referred to as model based coding.五、将下列句子翻译为相应的英文（每题 3 分，五个小题，共 30 分)1). 在测量应用中，选择合适的探头是获得最佳信号保真度的关键。
