(a) Create a random process 
where each sample of the random process is an IID, Bernoulli random variable equally likely to be
Form a new process according to the AR(2) model 
Assume 
(b) Compute the time-average autocorrelation function 
from a single realization of this process.
(c) Compute the ensemble average autocorrelation function 
from several realizations of this process. Does the process appear to be ergodic in the autocorrelation? (d) Estimate the PSD of this process using the periodogram method.
