  • What is the Fourier transform of a delta function?

    The Fourier transform of the delta distribution is the (distribution corresponding to) the constant function 1 (or possibly some other constant depending on normalization factor - but usually one wants F?=1 such that ? is the identity for convolution).22 nov. 2012

  • What is the Fourier transformation in 3D?

    The 3D Fourier transform
    It is based on the fact that for any 3D distribution of density g(x,y,z) there is a 3D Fourier transform volume G(u,v,w). If you take a projection through g to obtain a 2D image, it turns out that the Fourier transform of that image has the same values as slice through G.

  • What is the Fourier transform of the Dirac delta function proportional to?

    Then the Fourier transform of Dirac delta function can be evaluated to be ^?(p)=1?2? simply by applying such property to the definition of Fourier transform.
  • Since ??,f?=f(0) (this is the definition of ?), the unitary inverse Fourier transform of the Dirac delta is a distribution which, given a function f, evaluates the Fourier transform of f at zero. In other words, ?F?1(?),f?=1?2?????f(x)dx.
