Is Xt widesense stationary Find R tau E X t X t tau Simpli

Is X(t) wide-sense stationary? Find R, (tau) = E [X (t) X (t + tau)] Simplify the expression as much as possible. Write your final answer in the box.

Solution

B) TO CHECK x(t) wide sense ststionary or not ,x(t) is not given....

for wide sense statinary....x(t) should obeys the two principles.

1.mean of x(t)= constant.

2.AUTO CORRELATION should depend only on T(TOU).

C)ACF=INTG   [x(t)x(t1+T)]^t1+T _t1
