对中频信号的采用处理，以及速率的转换等，其中使用低通滤波器(The adoption of the IF signal processing, as well as the rate of conversion, in which the use of low-pass filter)

针对带时滞二阶振荡环节的系统传递函数,我们这里研究了,二阶振荡环节时间常数增大,对系统动态性能的影响,读者可以在程序上对时间常数进行修改,即可得出比较与区别.(brought against Delay second oscillation link system transfer function, we studied here, and the second time constant oscillation links increased, the dynamic properties of readers, the procedure for amending time constant can be obtained by comparison with distinction.)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

说明：  基于想要的主成分数量和精确度，采用matlab的pca函数进行主成分分析(Based on the desired principal component and accuracy, PCA function of MATLAB is used for principal component analysis)

基于MATLAB的算法，以及其作用在数学领域的应用与研究(MATLAB-based algorithm, and its role in the field of application and research of mathematics)

产生一个有带内相位噪声，毛刺噪声，白噪声的LO信号。(creative a LO signal with in band phase noise， spurs and noise floor.)

说明：  这是关于层次分析法、聚类分析、主成分分析的源代码(This is about the level of analysis, cluster analysis, principal component analysis of the source code)
