程序
说明： 1、基带码型仿真
（1）通过仿真观察占空比为50%、 75%以及100%的单、
双极性归零码波形以及其功率谱，分析不同占空比对
仿真结果的影响。
（2） 通过仿真产生一随机消息码序列，将其分别转换为
AMI码和HDB3码，观察它们的波形及其功率谱密度。
2、数字带通调制系统仿真
设计一个采用2ASK（ OOK） 调制的数字通信系统：
产生二进制随机数据，并仿真其对应的2ASK调制波形，
分析其频谱。所产生的调制波形加入不同信噪比的白噪声，
选取合适的接收方案，画出系统误码率曲线，并与理论误
码率进行对比。(1.Baseband pattern simulation
2. Simulation of digital band-pass modulation system)

DMX 512协议是Digital Multiplex的缩写，是灯光行业数字化设备的通用信号控制协议，同时也是是一种国际协议。 USITT DMX512/1990是调光和灯光控制台数据传输标准，是娱乐灯光领域常用的控制协议。以前0-10V模拟控制用的比较多，现在DMX512是娱乐灯光行业最主要的控制协议。USITT DMX512/1990是由美国剧场技术协会USITT提出的。最原始的版本出版于1986年，在1990年做了修改。 (DMX 512 protocol is short for Digital Multiplex is light industry, general-purpose digital signal device control protocol, but also is an international agreement. USITT DMX512/1990 is dimming and lighting control data transmission standard, is commonly used in the field of entertainment lighting control protocol. 0-10V analog control previously used more, now is the entertainment lighting industry, the main DMX512 control protocol. USITT DMX512/1990 by the American Association of Theater Technology USITT s. The original version published in 1986, was revised in 1990.)
