[sdiy] gaussian noise related to white noise

[Fredrik Carlqvist]

I would define white noise as 'any value in [-1,1]' (or som other interval)
with equal probability, i. e. with rectangular distribution. Gaussian noise
is then achieved by summing several of these sources. Just like the sum of
several rectangularly distributed stochastic variables approaches a gaussian
distribution.

AFAIR the relation between gaussian noise and white
noise was, that the pure random white noise (equal probability for all
possible amplitude values) gets to the bell curve via averaging, i.e. low
pass filtering.

What are the design specs for such a lowpass.
I think I knew it, but I can't remember, 
I guess I'm getting old.
