How To Get Frequency Of Fft. Find the frequency components of a signal buried in noise and find the amplitudes of the peak frequencies by using fourier transform. If you are looking at the magnitude results from an fft of the type most common used, then a strong sinusoidal frequency component of real data. If you use a gaussian windowing function, and then fit a parabola to the highest three points in your fft, you can get a theoretically exact. Use fft and ifft function from numpy to calculate the fft amplitude spectrum and inverse fft to obtain the original signal. Assuming your 512 samples of the signal are taken at a sampling freqeuncy $f_s$, then the resulting 512 fft coefficients correspond to frequencies: Time the fft function using this 2000 length. If you have the signal processing toolbox, you can use periodogram to get a power spectrum or power spectral density estimate.
