[Openeeg-list] Analog vs Digital

[Dr. S. <drs...@gm...>]

I have some questions about analog vs digital. Basically what does it mean
in terms of what the ups and downs are of the unit? I found lots of
information from various sources about theoretical aspects of the digital
and analog EEG, even some differences on how the software or hardware needs
to handle them. But nothing really of relevance that would allow a noob
like me a make a decision in what I need for the sake of purchasing.

A few questions floating around in my head are:

1. Is analog better quality? Digital seems like it transforms the signal
somewhat from its original means. Could this diffrence be heard in audible
quality, for example if you put the eeg signal into speaker (yes of course
after translating the signal into the audible range and then amplifying it
etc. etc.) Would they sound the same?

2. Is there some difference in what the application is? Does certain
aspects of software only work with digital or analog?

3. What do people generally use and why?

Thanks for your help.
