The very first question is the following:
> "What class of continuous signals has the greatest possible entropy
for a given variance (or power level?)"
Ok - so that's gaussian, IE p(x) has a gaussian distribution. In notes,
and easy.
> "What probability density function describes the excursions taken by
such signals from their mean value?"
Umm. Do I get two marks for saying gaussian or "the tails of a
gaussian", or am I missing the point?
