几种编码方式
- A. 产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2；B. 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50%，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列）；C. 改用HDB3码，画出前20个符号对应的波形；D. 改用密勒码，画出前20个符号对应的波形；E. 分别对上述1000个符号的波形进行功率谱估计，画出功率谱；F. 改变信源“0”的概率，观察AMI码的功率谱变化情况；-have a length of 1,000

- What would you do if you have got a couple broken Switch Mode Power Supplies, a screw driver and some curiosity!? Well obviously you would crack it open and try to figure it out. I have to admit, we would probably have opened them before they were ev
