Hi, I've defined an integral transform that I'll call T (obviously very similar to the Fourier transform):
[tex]T[f(x)](k)=\int_{-\infty}^\infty e^{- 2 \pi i k (x-a)}f(x)dx=\int_{-\infty}^\infty e^{- 2 \pi i k x}e^{ 2 \pi i k a}f(x)dx[/tex]
where a is a given parameter. perhaps we can call this the "a centered Fourier transform". I'm having trouble finding the inverse [tex]T^{-1}[/tex]
I've looked through the Fourier inversion theorem (though I'm having some trouble understanding it completely), and I can't really tell if that's useful for me.
Any help is appreciated.
