ListFourierSequenceTransform

ListFourierSequenceTransform[list,ω] gives the discrete-time Fourier transform (DTFT) of a list as a function of the parameter ω.

ListFourierSequenceTransform[list,ω,k] places the first element of list at integer time k on the infinite time axis.

ListFourierSequenceTransform[list,{ω1,ω2,…},{k1,k2,…}] gives the multidimensional discrete-time Fourier transform
