相互相関函数のFourier変換

$ \mathcal F(f\star g)(\omega)=\mathcal F(f)(\omega)^*\mathcal F(g)(\omega)

$ \mathcal F(f\star g)(\omega)=\mathcal F(f(-t)^**g(t))(\omega)

$ = \mathcal F(f(-t)^*)(\omega)\mathcal F(g)(\omega)

$ = \mathcal F(f^*)(-\omega)\mathcal F(g)(\omega)

$ = \mathcal F(f)(\omega)^*\mathcal F(g)(\omega)
