Symmetry property

The fact that the auto-correlation function R X X {\displaystyle \operatorname {R} _{XX}} is an even function can be stated as R X X (t 1, t 2) = R X X (t 2, t 1) ¯ {\displaystyle \operatorname {R} _{XX}(t_{1},t_{2})={\overline {\operatorname {R} _{XX}(t_{2},t_{1})}}} respectively for a WSS process: R X X (τ) = R X X (− τ) ¯. {\displaystyle \operatorname {R} _{XX}(\tau)={\overline {\operatorname {R} _{XX}(-\tau)}}.}
