总体平均经验模态分解EEMD程序可用于信号进行时频分析，比EMD程序更好用。-The overall average empirical mode decomposition EEMD program can be used to signal time-frequency analysis, better than the EMD program.

EMD与EEMD程序，经验模态分析程序，亲自检验，很好用(EMD and EEMD procedures, empirical modal analysis procedures, personally tested, very useful)

weltch窗函数滑动平均法，适合于初学信号处理的读者(Moving average of weltch window function.it is suitable for the readers who fistly learn the signal processing)
