X(t) is a wide sense stationary stochastic process with autocorrelation function RX (τ ) = 10 sin(2π1000t)/(2π1000t). The process Y(t) is a version of X(t) delayed by 50 microseconds: Y(t) = X(t - t0) where t0 = 5 × 10-5s.
(a) Derive the autocorrelation function of Y(t).
(b) Derive the cross-correlation function of X(t) and Y(t).
(c) Is Y(t) wide sense stationary? (d) Are X(t) and Y(t)jointly wide sense stationary
