Web1 Answer. Sorted by: 1. If you use the DFT formula, you get: Y [ k] = ∑ n = 0 2 N − 1 y [ n] e − 2 π k n 2 N. Now, substituting the definition of y [ n] you get: Y [ k] = ∑ n = 0 N − 1 x [ n] e − 2 π k ( 2 n) 2 N = ∑ n = 0 N − 1 x [ n] e − 2 π k n N. So, for 0 ≤ k < N you get that. http://www.phys.ufl.edu/~coldwell/Fourier/DFT%20code.htm
