This worksheet implements Welch's method of spectral estimation. This approach involves

  • dividing the signal into overlapping segments
  • windowing each overlapping segment and taking the FFT
  • average the results of the previous step
Welch's method attenuates the effect of signal noise on spectral estimation, but at the expense of reducing frequency resolution.
