Lecture 11: Discrete-time Fourier transform
ocw.mit.eduier transform, the discrete-time Fourier transform is a complex-valued func-tion whether or not the sequence is real-valued. Furthermore, as we stressed in Lecture 10, the discrete-time Fourier transform is always a periodic func-tion of fl. If x(n) is real, then the Fourier transform is corjugate symmetric,
