课堂作业 一、Translation these sentences bellow into English. 1、发射机（transmitter）通常是由几部分组成。 A transmitter consists commonly of several parts. 2、这是一个8伏的电压。 This is an 8-volt battery 3、电广泛地应用在工农业之中。 Electricity is widely used in industry and agriculture. 4、电流的单位是安培。 The unit of current is the ampere. 5、这里的两台设备质量都很好。 Both the devices here are good in quanlity. 6、必须弄清（find）解这个方程需要多长时间。 It is necessary to find how long a time is required to solve the equation. 7、这两个数值之差（difference）为万分之十三。 The difference between the two numbers is 13 parts in 104. 8、在前4章中，第三章最重要。 Of the first four chapters, the third chapter is the most important. 9、解这道题很容易。 This exercise can be solved with great ease 10、在这种情况下，电流导前（lead）电压90度。 In this case, current lead voltage by 90 11、若x1,则该方程无解。 For x1,the equation has no solution. 12、在把这些值代入(substitute)后，人们发现v就等于光速（velocity of light）。 Upon substituting these values, one finds that v is equal to the velocity of light. 13、这些波只朝一个方向传播。 These waves travel only in one direction. 14、这个系数（coefficient）有待于确定。 This coefficient remains to be defined. 15、计算机由于运算（operation）准确（accurate），速度快而得到了广泛的应用。 Accurate in operating and high in speed, computers are widely used. 16、我们将使用一根10米长的电缆（cable）。 We will use a cable 10 meters long. 17、我们对二极管的分析将是很有意义的。 Our analysis of diode will be meaningful. 18、交流电（AC）可以转变为直流电（DC），这一过程称为整流（rectification）。 19、万用表（multimeter）是测量电流、电压、电阻的仪表（instrument），它广泛地用在与电有关的（have connection with）工作中。 20、该曲线（curve）显示了导电率（conductivity）随温度的增加而下降的情况。 DSPs are available in two major classes: fixed point and floating point. The fixed point class represents real numbers in a fixed number of bits. The position of the binary point (similar to the decimal point) can be controlled by the programmer, and determines the range of numbers that can be represented. As the range increases, though, the available precision goes down, since fewer bits lie to the right of the binary point. In 16 bits, the formats 16.0, 15.1, 14.2, 13.3, 12.4, 11.5, 10.6, 9.7, 8.8, 7.9,
