how to solve this problem

2. A random process is given by y(t) = X(t) . cos wot + @ - where XIE) i's a wide- sense stationary process that amplitude modulates a carrier of a constant angular frequency, wo, with ra random phase @ independent of Act) and uniformly distri buted on (- 11 , + 11 ) . 1. 1. Determine the expected value, E [YCE)] 2. 2. Find the autocorrelation function of y (t), Ryy ( 2) 2. 3. Comment if Y(t) i's a wide- sense stationary? HINT : find E [Y(+)( first
