(2) Problem 5-5.3 A random process has sample functions of the form S x(t)= AF-T-10 11=180 where A and T are constants and to is a random variable that is uniformly distributed between 0 and T. The function f(t) is defined by f(t) = 1 0sts T/2; 0 Elsewhere Note, for a uniform distribution, pdf(to)=1/T 0≤ to ≤ T; 0 Elsewhere Z a. Find the mean and second moment. b. Find the time average and squared average. c. Can this process be stationary? d. Can this process be ergodic?
