filterbank(raw, frequency_bands, drop_original_signals=True, **mne_filter_kwargs)¶
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: Instance of mne.io.Raw
