Empirical mode decomposition(EMD) is a signal processing technique to decompose data set into several intrinsic mode functions(IMF) by a sifting process.

经验模式分解（EMD）通过筛分过程将原始信号分解成若干个基本模式分量（IMF），可看作无需预设带宽的自适应高通滤波方法。

Using Victorian machinery means the flour produced has to be wholemeal (to make brown or white, for example, would involve sifting out the bran, a process beyond traditional watermill technology), which goes into such products as the home-baked bara brith, a Welsh fruitcake made with dried fruit soaked in tea.
