WitrynaEssentially, it is a method of “screening” signal sequences. A series of intrinsic mode functions (IMF) of various frequencies are created by using an algorithm to gradually extract various scale fluctuation factors from high frequency to low frequency in signal sequences. The mode aliasing phenomena is where the EMD approach falls short.
