pybic.SpecToBispec

pybic.SpecToBispec(spec, v=[0, 0, 0], lilguy=1e-06)[source]

Estimate auto-bispectrum/-bicoherence spectrum from spectrogram(s).

Parameters:

spec (ndarray) – Input spectrogram.
v (list of int) – List of time-series’ indices to analyze.
lilguy (float) – Small value to avoid 0/0 errors.

Returns:

b2,B = SpecToBispec(...)

b2 (ndarray) - Bicoherence spectrum.
B (ndarray) - Bispectrum.

Return type:
