该m文件是数字信号处理实验课上的实验8：音频频谱分析仪的设计与实现(The m-file is an experimental digital signal processing on the experimental class 8: Audio Spectrum Analyzer Design and Implementation)

单位反馈二阶系统，采用比例加微分控制，提前对系统产生修正(Order unity feedback system that uses proportional plus derivative control, in advance of the system to produce correction)

ICA(独立成分分解),可实现采集信号中源信号的分离，便于提取特征量，实现模式识别。同时由于可以将源信号分离开来，可实现信号的降噪，去掉基波、三次谐波、五次谐波等(ICA (independent component decomposition) can realize the separation of the source signals in the acquisition signal, and facilitate the extraction of the feature quantity, and realize the pattern recognition. At the same time, because the source signal can be separated, it can realize the noise reduction of signal, remove the fundamental wave, the three harmonic, the five harmonic, etc.)

分别利用Monte Carlo 方法中的均匀抽样和重要抽样计算定积分(The use of Monte Carlo methods are uniform sampling and importance sampling to calculate definite integrals)

说明：  蒙特卡洛简单示例，适合初学者，简单容易，吐血整理(Monte Carlo simple example, suitable for beginners, simple and easy, vomiting blood)

least squre identification method

to find the discrete fourier transform using the fast fourier algorithm, any sequence of lengths which are multiples of 2 simply append zeros to satisfy this requirement

小数据量法计算最大lyapunov指数工具箱，原来的那个工具箱中有点误差，现在改进了只对前一部分直线状数据进行计算，使结果更加准确(A small amount of data calculated index of the largest lyapunov toolbox, the original error that the toolbox a bit, and now has improved only in a straight line like the first part of the data is calculated so that the results more accurate)
