Title: 10M resistor and 0R resistor on EEG-SMT
Post by: ellecieffe on June 05, 2013, 07:00:01 pm
Hi, I've not understand the functioning of NA(10M) resistor in HF rejection bolck of EEG-SMT. The same for 0R(NA) in the supply circuit. 

I haven't found these in modularEEG schematic. Why do you have  added them?

Thanks

Hello ellecieffe,

NA means they are not mounted. These pads were used initially only.

Best regard,
