WebA white noise has the property to have its autocorrelation function that is equal to E[f(t + τ)f(t)] = σ2δ(τ). We say that random signals can be Gaussian white noise, but for me if the signal has a Gaussian distribution it is necesseraly a white noise because as soon as we know the distribution then E[f(t + τ)f(t)] is automatically determined. WebCross-correlation Yjt is a (second-order) stationary process with µj = E(Yjt) and σ2 j = Var(Yjt).
