用于时间序列的功率谱分析 power spectrum

这种小波构造方式适合于各种DB系列的小波，但面对db6等比较长的小波，则均衡器的权长要足够长(Wavelet way that is suitable for a variety of wavelet DB series, but in the face of such a long db6 wavelet, it' s the right balance should be sufficiently long length)

Welch功率谱密度是用改进的平均周期图法来求取随机信号的功率谱密度估计值。Welch法采用信号重叠分段、加窗函数和FFT算法等计算一个信号序列的自功率谱估计(PSD如上例中的下半部分的求法)和两个信号序列的互功率谱估计（CSD）。MATLAB信号处理工具箱函数提供了专门的函数PSD和CSD自动实现Welch法估计，而不需要自己编程。(method of power spectral density plot )
