Prove the following two properties of the autocorrelation function R_X(?) of a random process X(t):

(a) If X(t) contains a DC component equal to A, then R_X(?) will contain a constant component equal to A².

(b) If X(t) contains a sinusoidal component, then R_X(?) will also contain a sinusoidal component of the same frequency.
