yes, makes sense to me, all signals in 'reallife' i have encountered so far
are rather 'analog' but can be represented in binary computing depending
btw, 'logic' signals in a binary computer are also 'analog'
I read somewhere that the 'upper' neuronal frequency is about 100Hz
does someone know if information is coded in this neuronal 'pulsation' ?
The thing im getting after is, if information is coded in amplitude
modulation (voltage levels)
AND some sort of frequence or pulse width modulation then one
should have to recalculate the processing power or 'capacity'
of the human mind.
