Webthe way to translate bin position in the FFT to Hz is as follows: f0_measure=28/ (Nffs/2)*fs/2 = 27.3437 the peak on the FFT bin 28 is equivalent to frequency 27.3437 Hz. The added noise is complex, so it's going to affect both phase and amplitude. The error on the frequency measurement is abs (f0-f0_measure) = 1.343750000000000 2.- bandera bereber
