Homework Help: Sampling low pass filtered white noise

  1. Dec 25, 2013 #1
    1. The problem statement, all variables and given/known data

    If we filter out ideal white noise using an ideal LPF of cutoff frequency W Hz and then sample it at F Hz , What are the conditions for different F so that the resulting discrete signal is correlated, uncorrelated , statistically independent and orthogonal etc?
    I would like to know the statistical behaviour of the output signal.

    2. Relevant equations

    3. The attempt at a solution

    I don't know where to start. But I think that if sampling frequency is lesser than nyquist frequency, the output is correlated.
