Abstract
The approach to Gaussianity of the output 
of a narrow-band system 
is investigated. It is assumed that the input 
is an 
-dependent process, in the sense that the random variables and 
are independent for 
. With 
and 
the distribution functions of and of a suitable normal process, a realistic bound 
on the difference 
is determined, and it is shown that 
as the bandwidth 
of the system tends to zero. In the special case of the shot noise process begin{equation} y(t) = sum_i h(t - t_i) end{equation} it is shown that begin{equation} mid F(y) - G(y) mid < (omega_o/lambda) frac{1}{2} end{equation} where 
is the average density of the Poisson points
