# Question: Let X t be a wide sense stationary Gaussian random

Let X (t) be a wide sense stationary Gaussian random process and form a new process according to Y (t) = X (t) cos (ωt + θ) where ω and θ are constants and is a random variable uniformly distributed over [0, 2x] and independent of X (t).

(a) Is Y (t) wide sense stationary?

(b) Is Y (t) a Gaussian random process?
