Fourier Transform is by definition using complex numbers.As far as the math aspect is concerned -- I know ;) My question was more, is it in practice used that way or is it somehow hidden like e.g. with Fourier series when one splits off the cos and sin parts of the fourier series that is basically a complex series too.
