On the left we present the EMD decomposition of an EEG signal. The decomposition for the signal in question generated 7 IMF. On the right we present an EEG signal filtered in frequency bands. It is interesting to note that the 1st IMF has a frequency very similar to the beta filtered signal, while the IMF 2 resembles the signal composition in the alpha and theta bands.
