The power spectral density of a real stationary random process \(\rm X(t)\) is
\(\rm {S_{XX}}\left( f \right) = \left\{ {\begin{array}{*{20}{c}} {\frac{1}{w};\left| f \right| \le w}\\ \rm {0;\left| f \right| > w} \end{array}} \right.\)
Value of \(\rm E\left[ {\pi X\left( t \right)X\left( {t - \frac{1}{{4w}}} \right)} \right]\) is
