快速傅里叶变换 (FFT) 实现，给定信号x(t)=sin(2πf0t)，f0=50Hz，对x(t)以fs=200Hz进行抽样，抽样点数为N=16。编写程序实现对x(n)的快速傅里叶变换，求得相应的X(K)。(Fast Fourier Transform (FFT) to achieve a given signal x (t) = sin (2πf0t), f0 = 50Hz, for x (t) with fs = 200Hz sampling, the sampling points is N = 16. Procedures for the preparation of x (n) of the fast Fourier transform, obtained by the corresponding X (K).)

这是我强烈推荐的一本书，它是基于开源软件做的类似于matlab的一个工具，功能非常的强大，建议在校学生好好学习这门课，对于以后的应用会有很大的帮助(python)

关于谱估计的MATLAB源程序，含各种谱估计的对比(MATLAB source code on the spectrum estimation)

对信号进行小波包分解，得到节点的小波包系数。然后对每个节点系数进行重构。(Wavelet packet decomposition is used to get the wavelet packet coefficients of the nodes. Then the coefficients of each node are reconstructed.)

说明：  利用MATLAB语言，实现EMD分解，得到各个IMF分量，再重组降噪(Using MATLAB language, EMD decomposition is realized, IMF components are obtained, and then noise reduction is recombined)
