EMD decomposition of two waves signal, (a) sum of two waves, (b) lower and upper envelopes (red) and their mean (blue), (c) the first IMF and (d) the first ...

As can be clearly seen, the decomposition removes the high-frequency components of the signals first, and then sifts down to the mean trend of the signal.
