Fourier Transform--GaussianThe Fourier Transform of a Gaussian Function is given by
The second integrand is Even, so integration over a symmetrical range gives 0. The value of the first integral is givenby Abramowitz and Stegun (1972, p. 302, equation 7.4.6)
so a Gaussian transforms to a Gaussian.See also Gaussian Function References
