Forward dft
WebReview of the complex DFT. The classic discrete Fourier transform (DFT) operates on vectors of complex numbers: Suppose the input vector has length n. The output vector will also have length n. Let ω (omega) be a primitive n th root of unity. In other words, ωn = 1, but ωk ≠ 1 for all integers 1 ≤ k < n. The standard choice for the DFT ...
