It is desired to estimate the mean value of a stationary random process by averaging N samples from the process. That is, let 1 N Derive a general result for the variance of this estimate if: X = X₁ a) The samples are uncorrelated from one another. b) The samples are separated by Ar and are from a random process having an autocorrelation function of Rx (T).
