有幾題的富立葉轉換想問問
以下都用英文 怕翻譯之後會失去原意
1.Determine the effect of a shift ofθ' on the Fourier-Bessel transform of
a function f(r,θ).
2.Calculate the combined effect of a scaling(by a) and rotation (by θ) on
the Fourier transform of the function f(x,y),where f(x,y) is a 2-D rect
function.
3.If FT[(x,y)]=F(u,v), show that (∫-∞~∞∫-∞~∞f(x,y)dxdy/f(0,0))=(F(0,0)/
∫-∞~∞∫-∞~∞F(u,v)dudv)
