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?
