Let the Laplace transform of a function f(t) which exists for t > 0 be F1(s) and
the Laplace transform of its delayed version f(1 - $$\tau$$) be F2(s). Let F1*(s) be the
complex conjugate of F1(s) with the Laplace variable set as $$s=\sigma\;+\;j\omega$$. If G(s) =$$\frac{F_2\left(s\right).F_1^\ast\left(s\right)}{\left|F_1\left(s\right)\right|^2}$$
, then the inverse Laplace transform of G(s) is
