In the plot squared length of Fourier coefficients vs frequency, the peak gives the strongest frequency. does it give the accurate value of period?? Is it like a single frequency in frequency domain corresponds to a range of periods??

  • $\begingroup$ @YuvalFilmus, do you mean it is not a question in computer science? $\endgroup$ – usul Mar 13 '14 at 20:32
  • $\begingroup$ @usul I'd say it's electrical engineering, though signal processing is definitely used by people working in CS departments. $\endgroup$ – Yuval Filmus Mar 14 '14 at 2:15
