Let A and B be two independent Gaussian random variables with mean 2 and variance 5, and let { X n } be a discrete-time random process defined as, A, for n even XIn = B, for n odd Is { X [n]} stationary? Is { X[n]} wide-sense stationary? O Wide-sense stationary but not stationary O Neither stationary nor wide-sense stationary O Stationary but not wide-sense stationary O Both stationary and wide-sense stationary
