Unformatted text preview: random variables, each uniformly distributed on [−1, 1] . Find the mean and autocorrelation functions for X (t ) . Is X (t ) wide- sense stationary? 3. Let M (t ) be a mean- zero, wide- sense stationary random process whose power spectral density SM ( f ) is zero for f > B . Let Θ be a random phase angle that is uniformly distributed over the interval 0 ≤ θ < 2π and is independent of M (t ) . Define the DSB- SC signal X (t ) = Ac M (t ) cos ( 2π fc t + Θ) wh...
