Web1 Answer Sorted by: 2 Final step is pretty straightforward. All you need to do is to apply the Hilbert Transform to each IMF and extract the instantaneous frequency from analytical signal. Instantaneous frequency is given by: ω ( t) = d ϕ ( t) d t where ϕ ( t) = a r g [ x a ( t)] (unwrapped phase of the analytical signal).
