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 )

KEB COMBIVERT The MS-Repeater (Part. No.: 00.F4.072-2008) is for connection and amplification of incremental encoder signals during master-slaveoperation.

基于平移不变小波变换的电力时间序列预测，结合多层感知器（MLP）神经网络， 预测精度很好。(Electricity demand time-series forecasting program Based on shift-invariant wavelet transform features )
