I have calculated a k-space function to be f(k) = [itex]\frac{1}{2k}[/itex]
I want to Fourier transform this to find f(x), I have found many different Fourier transform equations...can I use this one?
f(x) = [itex]\frac{1}{\sqrt{2π}}[/itex][itex]\int[/itex][itex]\frac{1}{2k}[/itex]e-ikxdk Limits fo integration -Infinity to Infinity
I'm also having trouble remembering my complex analysis, would I use residue theorem for this integral? I don't quite remember exactly how that goes...
∫f(z) = 2πiRes(f,z0) Correct?
The residue for f(k) is 1/2, so I am not sure excatly what the answer means? Or if I am using residue theorem correctly?
Final answer: f(x) = [itex]\frac{1}{\sqrt{2π}}[/itex]2πi(1/2) = [itex]\sqrt{\frac{π}{2}}[/itex]i
This doesn't make sense as an answer.
Thanks,
Jason
