Hi,
I have a one-dimensional N-coordinate periodic Gaussian kernel defined by
dnorm(c(0:N/2,(N/2-1):1),sd = h)
where h is the bandwidth/smoothing parameter/FWHM.
I want to calculate the Fourier transform of this, which can be done using a
FFT. But my question is: is it possible to get the Discrete Fourier transform
of this sequence analytically? Do there exist references on this?
Many thanks and best wishes,
Aarem
