providing ambulatory solutions Is there a notch filter option anywhere (for say 60Hz) and if not would it be better to use a lowpass filter of 50 or 60Hz?
There is NO notch at 50/60 Hz. Normally, with low impedances, you should not have 60 Hz; but, if so, you could use the Preprocessing Moving Average filter at 64 Hz for a reduction of 60 Hz of globally a factor 10.
