"WebThe spectrum tools in EMD can be used to explore cross-frequency interactions in oscillatory signals. The simplest approach is to look at how the phase, frequency or amplitude of a high-frequency signal interacts with the phase of a low frequency signal. This can be extended into 2 or 3 dimensions by exploring the relationship between low ... " - Hilbert huang emd
