DIRAC DELTA FUNCTION AS A DISTRIBUTION
web.mit.eduThe Fourier transform of this distribution is then defined by applying the same distribution to the Fourier transform of the test function, so ˜ T f [ϕ] ≡ T f [˜]= ∞ −∞ pe ipa ˜ ϕ (p). (4.11) But the inverse Fourier transform is given by ϕ (x)= 1 2 π ∞ −∞ d pe ipx ˜ ϕ (p), (4.12) so by comparing the two formulas above ...
