程序

（一）基本任务：单频正弦波模拟信号的简单数字化。即对一个单频正弦波模拟信号进行抽样、均匀量化、PCM二进制自然编码。 1、主要步骤和要求： （1）单频正弦波模拟信号的抽样实现。要求输入信号的幅度A、频率F和相位P可变；要求仿真时间从0到2/F，抽样频率为Fs=20F；要求给出抽样信号samp的波形图。 （2）单频正弦波模拟信号均匀量化的实现。要求对抽样信号sampl归一化后再进行均匀量化；要求量化电平数D可变；要求输出信号为平顶正弦波；要求给出量化输出信号quant的波形图，并与抽样信号samp画在同一图形窗口中进行波形比较。 （3）单频正弦波模拟信号PCM二进制自然编码的实现。要求按量化序号给出PCM二进制自然编码；要求给出编码后的数字序列pcm。 (err)

Profibus是作为德国国家标准DIN 19245和欧洲标准prEN 50170的现场总线。ISO/OSI模型也是它的参考模型。由Profibus -Dp、Profibus -FMS、Profibus-PA组成了Profibus系列(Profibus is the field bus of German national standard DIN 19245 and European standard prEN 50170. The ISO/OSI model is also its reference model. Profibus series is composed of Profibus-Dp, Profibus-FMS and Profibus-PA.)
