My question has to do with integrating gaussian noise.

Let us assume we have samples of discrete gaussian white noise with mean $$\mu = 0$$ and variance $$\sigma_{th}^2$$. If theseThese noise samples are passed through a summer that implements the operation $$$$y=\sum_{n=0}^{N-1}x[n]$$$$

($$x$$ issystem shown in the inputFigure (a cascade of two integrators with outputs $$y_1[n]$$ and $$y$$ is the output)$$y_2[n]$$, we would expect that the output to be white gaussian noise (Central Limit Theorem?respectively). If the output of this summer is now passed through another summer,

What will be the outputmean and variance of that summer also be a gaussian process with $$\mu=0$$, or will the resultant waveform have some DC component now$$y_1$$ and $$y_2$$ (let us say after $$N$$ cycles)?
