WebDec 3, 2014 · While I'm not familiar with FFTW it is based on using the discrete Fourier transform. If you need the first harmonic at 20 Hz, then the sample period must be 1/20 = 0.05 sec. To get results to 20 KHz the sampling frequency must be at least 40 KHz. So the number of samples is N=0.05*40000=2000 (or probably 2048 for the FFT). mtc wellness llcWebFFTW Meanings What Does FFTW Stand For?
