WebFor properly bandlimited data sampled at F s, the frequency range is 0 to F s / 2. Divide F s / 2 by N / 2, and you get F s / N as the frequency spacing of 1 + N / 2 equally spaced DFT results, including both end points, DC and F s / 2. So F s / N is the DFT result bin spacing of an N -point DFT. However, the actual resolution can range from a ...
