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 random binary sequence, "0" with a probability of 0.8, "a" with a probability of 0.2; B. above zero AMI data coding, and pulse width of symbols width of 50%, waveform sampling rate Symbol rate for the eight times that he painted before the 20 symbols corresponding waveforms (also given before 20 Source sequence); C. HDB3 code switch to depict the former 20 symbols corresponding waveform; D. Miller to switch codes to depict the former 20 symbols corresponding waveform; E. respectively above 1,000 symbols for the power spectrum waveform estimated to depict the power spectrum; F. Change source "0" the probability to observe AMI code changes in the power spectrum;

ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels. Lenient thresholds give high sensitivity but low specificity, strict thresholds give high specificity but low sensitivity the ROC curve plots this trade-off over a range of thresholds (usually with sens vs 1-spec, but I prefer sens vs spec this code gives you the option). It is theoretically possible to operate anywhere on the convex hull of an ROC curve, so this is plotted too. The area under the curve (AUC) for a ROC plot is a measure of overall accuracy, and the area under the ROCCH is a kind of upper bound on what might be achievable with a weighted combination of differently thresholded results from the given classifier -ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels.
