    Inverse Fourier Transform

    Hey, how you doing guys.

    Does anyone know how to apply Fourier Inverse tranform to this paticular Eq.

    7*Sinc^2(2w-3)

    Thanks in advance and Greets from Mexico!

    Lorenzo,
    I assume what you mean by "7*Sinc^2(2w-3)" is:

    h(w) = 7 { \left ( \frac{sin \left ( 2w - 3 \right ) }{2w - 3 } \right ) }^{2 }

    Consider the inverse Fourier sine transform:

    f(x) = \sqrt[ ]{ \frac{2 }{ \pi }} \int_{ 0}^{ \infty } h \left ( w \right ) sin \left ( wx \right ) dw

    Personally though... I couldn't solve it. Neither could Mathematica.
