So we know shot noise is given by the formula
i_n^2 = 2*e*I_avg*BW
Where e is the electron charge and BW is the bandwidth.
I’ve been trying to derive the factor of 2 in the formula.
But I’m not quite getting it.
A typical derivation looks at random pulses measured over some time T.. thetricky part is relating the bandwidth to the time T. So here the author states that BW = 1/(2*T)
and says that’s related to the Nyquist sampling theorem.

But I don’t see it? Is that correct? Help!
TIA
