Question: Sinusoid with random phase . Consider the random process X(t )= A cos(0t+ ), where A and 0 are real constants and U (0, 2).

Sinusoid with random phase. Consider the random process X(t )= A cos(0t+

), where A and 0 are real constants and U (0, 2).

(a) Find the mean function E[X(t) ]and the autocorrelation function Rx(t+ , t). Is X (t) wide-sense stationary? Why?

(b) Assume now U(0,/2). Determine the mean-square value E[X2(t)]. Is E[X2(t)] deterministic? time dependent? Is the new random process X(t) wide-sense stationary? Why? If E[X2(t)] is time varying, what is its time average?
