WebNov 14, 2024 · When I run the Matlab script, I see the following: The actual frequency should be 15.2 (from my test script). In order to generate the FFT IP core, in my Quartus Project, I open the IP catalog, search for "FFT" and double click it. I give the core a name (test_fft_ip.qsys in this case), and set the parameters to the following: WebJul 4, 2024 · How to calculate Fourier transform for...

WebApr 11, 2024 · Y = fft (X); sum (X.^2)==sum (abs (Y.^2))/L. ans = logical. 0. sum (X.^2)-sum (abs (Y.^2))/L. ans = 9.0949e-13. shows it is equal to almost the double-precision. NOTA BENE: Remember that if pad the signal so that NFFT is >L, the divisor is still L, NOT NFFT since there's no power in the zero-padded elements. Sign in to comment.
WebMay 25, 2012 · Your Fs is 1000. So when you divide it by 2 & then multiply by values ranging from 0 to 1, it returns a vector of length NFFT/2+1. This vector consists of equally spaced frequency values, ranging from 0 to Fs/2 (i.e. 500 Hz). Since you plot using ' plot (f,2*abs (Y (1:NFFT/2+1))) ' command, your X-axis limit is 500 Hz.
