Passage B

). B. 70.9 C. 70.7 D. 14.1

The higher the frequency of the analogue signal, the more often it must be sampled. However, it is usually adequate to sample a signal at twice its highest frequency. Each binary digit used to show a binary value is known as a bit. The accuracy of conversion is limited by the number of binary bits used by the ADC . If the conversion is made using a four-bit ADC, only sixteen different binary values can be produced. The smallest value is 0000 and the largest is 1111. If an 8-bit ADC is used, then 256 different digital values can be produced. When a measurement of the analogue signal does not coincide with one of these binary values, it must be rounded up or down. 3. If the analogue signal is u=sin(200πt), then the adequate sampling frequency must be more than ( ). B. 100Hz C. 200Hz D. 50πHz ) different binary

A 50Hz.

4. If the conversion is made using a ten-bit ADC, ( values can be produced. A. 1024. B. 256 C. 512 D. 10

5. Explain the underlining word in Chinese according to the article. rounded up or down 二. Please translate following five passages into Chinese 将下列句子和段落翻译成汉语
(共 40 分,第小题每题 5 分)

1. Different signals are those that use two complementary paths carrying copies of the same signal in equal and opposite polarity.

2. There are several reasons to use FLASH memory instead of a hard disk: FLASH memory allows faster access. It is noiseless, lighter, and smaller in size and has no moving parts.

3.Digital signal processing is an essential element of countless home and business systems. Its domain can only increase as time proceeds. Thus , DSP is becoming an essential area of expertise for technologists and engineers.

4. Rise and fall time are measures of the time it takes the signal edge to make

a transition from one state to another. In modern digital circuitry, these values are usually several nanoseconds.

5. Bandwidth means the transmission capacity of an electronic pathway such as a communications line or computer bus . In a digital line , it is measured in bits per second or bytes per second. In a analog line , it is the difference between the highest and lowest frequencies and is measured in Hertz.

6 芯片就是一小片潜入了集成电路的半导体材料。 芯片的典型尺寸不超过 一个平方英寸, 却能包含几百万个晶体管。 芯片的类型多种多样。 例如, CPU 芯片内包含完整的处理单元,而存储芯片包含的是空白存储单元。

7.噪声限定了系统可以处理的数据信号。 噪声降低了放大器、 接受器等设 备辨别信号的能力——因为噪声和输入信号混合起来。运算放大器产生的 噪声、电阻噪声和电源噪声决定了能够恢复和测量的信号大小。

Many engineers look at tasks like troubleshooting and design as purely “measurement” challenges , and tend to think reflexively of their as the whole solution instruments have an important 2 1

solution that can drive a device-under-test with the industry-standard signals for acquisition .But only with a signal source can engineers really control what goes into the device. And that is often a necessity comes out of the device. 5 , the signal source makes margin testing and 4 making sense of what

Working with a signal source and oscilloscope or logic analyzer, engineers can explore the limits of their designs’ performance –introducing deliberate stresses with the source and measuring the results with the oscilloscope, or capturing data with logic analyzer when digital errors occur . 五.Translate the following paragraph into Chinese. 将下列段落翻译成汉语 (共 20 分) DSPs are programmed in the same languages as other scientific and engineering applications, usually assembly or C. Programs written in assembly can execute faster, while programs written in C are easier to develop and maintain. In traditional applications, such as programs run on personal computers, C is almost always the first choice. If assembly is used at all, it is restricted to short subroutines that must run with the utmost speed. However, DSP programs are different from traditional software tasks in two important respects. First, the programs are usually much shorter, say, one hundred lines versus ten thousand lines. Second, the execution speed is often a critical part of application.
