I have a question that is similar to this one but slightly different.
If I have discrete signal $$s(t) = \sum_k n_k \delta(t-kT_0),\quad k=0,1,\dotsc,$$ where $n_k$ are just some scalar numbers. What is the Fourier transform of $s(t)$? I think it should be some kind of a convolution $$S(f) = G(f)\star\sum_m\delta(f-m/T_0),\quad m=0,1,\dotsc,$$ but what is $G(f)$? Is there an analytical expression for it in terms of $n_k$?
