Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

I am calculating the Fourier transform of the bessel function [tex]J_0^2(bx)[/tex] by using Maple. I tried two equations and get two results.

[tex]\int J_0^2(bx)e^{-j2\pi fx}dx=G^{2, 1}_{2, 2}\left(-1/4\,{\frac {{w}^{2}}{{b}^{2}}}\, \Big\vert\,^{1/2, 1/2}_{0, 0}\right)

{\pi }^{-1}{b}^{-1}[/tex]

and

[tex]\int J_0^2(bx)[cos(2\pi fx)-jsin(2\pi fx)]dx=G^{2, 0}_{2, 2}\left(1/4\,{\frac {{w}^{2}}{{b}^{2}}}\, \Big\vert\,^{1/2, 1/2}_{0, 0}\right)

{b}^{-1}[/tex]

I tried to plot these two functions but only the second one shows a plot. The first one does not show anything and it tells that could not evaluate the function in the variable range (e.g. 0..4).

Could anyone help me to verify this? I want to make sure that the two results are identical. If it is not, which one is correct so I may continue with other calculations of FFT on the bessel functions and on the Generalized geometric functions.

Thanks so much in advance.
