To use this DFT to get the magnitudes of the input at various frequencies, you'll need to divide the DFT output by N. To verify this, you can call Matlab's fft function and compare with your results. You should get the same answer from Matlab's fft. Note that Matlab's fft documentation says:

Webthe 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 … WebDigital Signal Processing - DFT Introduction. Like continuous time signal Fourier transform, discrete time Fourier Transform can be used to represent a discrete sequence into its …
WebThe discrete Fourier transform (DFT) is a method for converting a sequence of \(N\) complex numbers \( x_0,x_1,\ldots,x_{N-1}\) to a new sequence of \(N\) complex numbers, \[ X_k … Web1 Answer. The simplest correct answer is that DFT is in O ( N e 3). This comes from the idea that you are ultimately diagonalizing a Hamiltonian with dimension proportional to the number of elections and diagonalization is technically O ( n 3). In reality, DFT is a bunch of steps and different steps are rate-limiting in different context. If we ...
