Hi
Does the cyton board apply any filter to the aquired data ? I am asking because I am interested on recording readiness potentials (bereitschaft potentials ) that have a very low frecuency ( around 0.5 Hz)
No filtering happens in the firmware. The OpenBCI_GUI recording files are also unfiltered. So yes, the very low band of EEG frequencies is available. However the GUI can be configured to show filtered data in the screen windows, but again the full recorded data is not filtered.
