meegsim.waveform.narrowband_oscillation

meegsim.waveform.narrowband_oscillation(n_series, times, *, fmin=None, fmax=None, order=2, random_state=None)

Generate oscillatory-like time series by filtering white noise in a requested frequency band.

Parameters:

n_seriesint

The number of time series to generate.

timesarray

Array of time points (each one represents time in seconds).

fminNone (default) or float

Lower cutoff frequency (in Hz). If None (default), 8 Hz are used as the cutoff.

fmaxNone (default) or float

Upper cutoff frequency (in Hz). If None (default), 12 Hz are used as the cutoff.

orderint, optional

The order of the filter. By default, the order is equal to 2.

random_stateNone (default) or int

Seed for the random number generator. If None (default), results will vary between function calls. Use a fixed value for reproducibility.

Returns:

outarray, shape (n_series, n_times)

Generated filtered white noise.
