1. (a) Sketch the ensemble of the random process X(t) = Acos(27rf0t + 9), where A is a uniform random variable EAT5, 5), and f0 = 100 and 6' = 0 are constants. (b) Choose two different time instants, for example, where (27rfot + 9] = ft and where (27rf0t + I9) = 1.511 Call these time instants t1 and :2. Plot a histogram of X (:1) and X (:2), by observing the realizations at these time instants
