Notch filter?
Posted: Mon Apr 25, 2016 9:41 pm
With other EEG equipment, I might run a notch filter at 60 Hz (in North America). But because the Biosemi system is battery operated, I am wondering:
1) Is it necessary with this system?
2) If so, should it be at 60 or 50 Hz?
3) Or should I do it at 60 Hz regardless/in addition to as that's what the other equipment in the room operates at (or its harmonics)?
