[Eeglablist] line noise re-revisited...again

[Paul Kieffaber]

Dear List,
I was discussing the line noise issue with someone recently and a
question came up regarding the point of introduction.  My understanding
is that most line noise is introduced to the recordings through the
cables between the electrodes and the A/D box or amplifiers.  Is there
also a risk of introducing line noise with long cables between amplifier
an the recording computer?

Our hunch is that the digital signal in those lines is not susceptible
to the introduction of noise like the analog signal between the scalp
and the amplifier.

Your thoughts and comments are appreciated.

Paul
