emd.cycles.normalised_waveform

emd.cycles.normalised_waveform(infreq)

Compute the time-domain waveform of an phase-aligned IF profile.

Parameters:

infreqndarray

instantaneous frequency profiles [samples x cycles] such as the output from emd.cycles.phase_align.

Returns:

ndarray

The normalised waveforms of the cycles in infreq

ndarray

A reference sinusoid of the same length as the input.
