Different electrode types might have different impedances, because.
R and C parts of the impedance will vary depending on electrode
area, material and used electrolyte / conductive gel.

However due to the high input impedance of the eeg-amplifier
different electrode impedances should not lead to different voltages.

So the input voltage range will essentially be the same for all
suitable electrode types.

Regards,

Joerg
