Question: Consider the random process ( n ) , consisting of two sinusoidal with white noise where the phases of the sinusoidal components are uniformly distributed

Consider the random process (n), consisting of two sinusoidal with white noise where the phases of the sinusoidal components are uniformly distributed (-,+) and uncorrelated with white noise. Give its power spectrum and the expected value of the periodogram.
