Let X (t) be a random process defined by X(t) ACosot + BSin @t, where A and B are independent and identically distributed (IID) random variables (as IID is defined for a random process). (a) Find the autocorrelation function, R, (4,t,). (b) Is this random process wide-sense stationary (WSS)? If not, under what condition it becomes WSS?
