Question: Consider the random process V ( t ) = cos ( t + ) , where is a random variable with probability density P (

Consider the random process V (t)= cos(t+), where is a random variable with probability density P()=1/2; and 0 else. a) Show that the first and second moments of V(t) are independent of time. b) If = constant, will the ensemble mean of V(t) be time-independent?
