braindecode.preprocessing.filterbank(raw, frequency_bands, drop_original_signals=True, order_by_frequency_band=False, **mne_filter_kwargs)[source]#

Applies multiple bandpass filters to the signals in raw. The raw will be modified in-place and number of channels in raw will be updated to len(frequency_bands) * len(raw.ch_names) (-len(raw.ch_names) if drop_original_signals).

  • raw ( – The raw signals to be filtered.

  • frequency_bands (list(tuple)) – The frequency bands to be filtered for (e.g. [(4, 8), (8, 13)]).

  • drop_original_signals (bool) – Whether to drop the original unfiltered signals

  • order_by_frequency_band (bool) – If True will return channels odered by frequency bands, so if there are channels Cz, O1 and filterbank ranges [(4,8), (8,13)], returned channels will be [Cz_4-8, O1_4-8, Cz_8-13, O1_8-13]. If False, order will be [Cz_4-8, Cz_8-13, O1_4-8, O1_8-13].

  • mne_filter_kwargs (dict) – Keyword arguments for filtering supported by Please refer to mne for a detailed explanation.
