Question: A random process is defined by: X (t) = (t) Acos (0t + ) Where u(t) is a unit step function, assuming that is uniform

A random process is defined by: X (t) = (t) Acos (0t + ) Where u(t) is a unit step function, assuming that is uniform over the interval (0, /2). Show that the root mean square of the process is given by E [X^2 (t)] = A^2u^2 (t) [(1/2) - (1/) sin(20t)]
