这是我学习时候，我的课本上的课后习题，我把他整理出来！希望大家能有所收益！(This is my study, my after-school textbook exercises, I took him out of order! Hope that we can get any benefit!)

dfig wind turbine model for all people

生成一个采样频率2000，由50Hz、120Hz、200Hz正弦信号以及噪声信号组成的数字信号，滤掉150Hz>f>100Hz的频率，计算并显示滤波前后的原始数据波形以及功率谱密度。(A sampling frequency of 2000, a digital signal composed of 50Hz, 120Hz, 200Hz sine and noise signals, is generated to filter out the frequency of 150Hz>f>100Hz and to calculate and display the original data waveforms and the power spectral density before and after the filtering.)

说明：  这个函数产生了归一化的基于逆DFT方法的瑞利采样。(This function generates normalized rayleigh samples based on Inverse DFT method)
