- mne.time_frequency.psd_array_multitaper(x, sfreq, fmin=0.0, fmax=inf, bandwidth=None, adaptive=False, low_bias=True, normalization='length', output='power', n_jobs=None, verbose=None)#
Compute power spectral density (PSD) using a multi-taper method.
array, shape=(…, n_times)
The data to compute PSD from.
The sampling frequency.
The lower frequency of interest.
The upper frequency of interest.
The bandwidth of the multi taper windowing function in Hz.
Use adaptive weights to combine the tapered spectra into PSD (slow, use n_jobs >> 1 to speed up computation).
Only use tapers with more than 90% spectral concentration within bandwidth.
- normalization‘full’ | ‘length’
Normalization strategy. If “full”, the PSD will be normalized by the sampling rate as well as the length of the signal (as in Nitime). Default is
