FR = Fmax/N (Bins) For a 44100 sampling rate, we have a 22050 Hz band. With a 1024 FFT size, we divide this band into 512 bins. FR = 22050/1024 ≃ 21,53 Hz. But I want to know more about 21,53 Hz. exactly FR.

Webb7 maj 2024 · First, you want to find the peaks in this 2D plot. In your case, you know that there will be 2 peaks in your FFT (because you added two sines). Your plot shows 4 peaks because the FFT magnitude is symmetric, since your signal is real. You can discard negative wave numbers and look for peaks among the positive wave numbers. Webb28 aug. 2013 · The FFT is a fast, O [ N log N] algorithm to compute the Discrete Fourier Transform (DFT), which naively is an O [ N 2] computation.
