Shut noise? Do you mean shot noise? Let's assume you do, because I have never heard of shut noise.
Code:I(ia) <+ white_noise(4*`P_Q*ic)
You've got it. Your right that
white_noise models a Gaussian process, but that is the right model for shot noise.
It is my understand shot noise is a Poisson process for individual electrons, but when considering the electrons in mass the distribution becomes Gaussian due to the law of large numbers. This is described in the
Wikipedia article on shot noise:
Quote:For large numbers, the Poisson distribution approaches a normal distribution about its mean, and the elementary events (photons, electrons, etc.) are no longer individually observed, typically making shot noise in actual observations indistinguishable from true Gaussian noise.
