A random process Y(t) is given by Y(t) = X(t) cos(?t + ?), where X(t), a zero-mean wide sense stationary random process with auto-correlation function RX(?) = 2exp(-2?|?|) is modulating the carrier cos(?t + ?). The random variable ? is uniformly distributed in the interval (0, 2?), and is independent of X(t). then the mean value of Y(t) is 1/2 .a 0 .b cos(?t) .c 1 .d

Step 1
We are given a random process \(Y(t) = X(t) \cdot \cos(\omega t + \theta)\), where \(X(t)\) is a zero-mean wide sense stationary (WSS) random process with auto-correlation function \(R_X(\tau) = Z \cdot \exp(-Z \cdot |\tau|)\). The random variable \(\theta\) is Show more…

A random process is given by: x(t) = A cos(wt + φ) Where: w is a constant. A and φ are independent random variables. The random variable A has a mean of 3 and a variance of 9. The random variable φ is uniformly distributed between 0 and π. 1- Find cov_xx(t,s). 2- Is x(t) is a wide-sense stationary process?
Given the random process X(t) = A Sin(ept + Θ) where A and Cp are constants and Θ is a random variable uniformly distributed on the interval (0, π), define a new random process Y(t) = X(t). Find the autocorrelation function of Y(t). Find the cross-correlation function of X(t) and Y(t). Are X(t) and Y(t) wide-sense stationary? Are X(t) and Y(t) jointly wide-sense stationary?
