mne.time_frequency.fwhm

mne.time_frequency.fwhm(freq, n_cycles)

Compute the full-width half maximum of a Morlet wavelet.

Uses the formula from Cohen[1].

Parameters:

freqfloat

The oscillation frequency of the wavelet.

n_cyclesfloat

The duration of the wavelet, expressed as the number of oscillation cycles.

Returns:

fwhmfloat

The full-width half maximum of the wavelet.

Notes

New in version 1.3.
