WitrynaThe FFT returns a two-sided spectrum in complex form (real and imaginary parts), which you must scale and convert to polar form to obtain magnitude and phase. The frequency axis is identical to that of the two-sided power spectrum. The amplitude of the FFT is related to the number of points in the time-domain signal. Use the following equation to WitrynaThe FFT algorithm reduces this to about (n/2) log 2 (n) = 512 × 10 = 5,120. multiplications, for a factor-of-200 improvement.
