But wait, it gets better (or worse?) 2.2 Frequency folding (or mirroring) It turns out the DFT also is symmetric about the m= N=2. Thus, the DFT is mirrored about the frequency ! m= ! N=2. In speci c math terms: The DFT provides a representation of the finite-duration sequence using a periodic sequence, where one period of this periodic sequence is the same as the finite-duration sequence. As a result, we can use the discrete-time Fourier series to derive the DFT equations.

In computing the DFT of real sequences it is possible to reduce the amount of computation by utilizing the fact that the sequence is real. In particular, The graph of arg X(f) against frequency is known as the phase spectrum. By copying a real digital signal into a complex sequence x[1..N], UNIT-I DISCRETE FOURIER TRANSFORM AND COMPUTATION. 1.

Let us consider a signal x n, whose DFT the DFT spectrum is periodic with period N (which is expected, since the DTFT spectrum is periodic as well, but with period 2π). Example: DFT of a rectangular pulse: x(n) = ˆ 1, 0 ≤n ≤(N −1), 0, otherwise. X(k) = NX−1 n=0 e−j2πkn N = Nδ(k) =⇒ the rectangular pulse is “interpreted” by the DFT as a spectral line at frequency ω = 0. For example, the DFT is used in state-of-the-art algorithms for multiplying polynomials and large integers together; instead of working with polynomial multiplication directly, it turns out to be faster to compute the DFT of the polynomial functions and convert the problem of multiplying polynomials to an analogous problem involving their DFTs. In this video, it demonstrates how to compute the Discrete Fourier Transform (DFT) for the given Discrete time sequence x(n)={0,1,2,3} The discrete Fourier transform or DFT is the transform that deals with a nite discrete-time signal and a nite or discrete number of frequencies.
