    • Application of FFT methods to wind wave data series by adding zeros 

      Varkey, M.J. (National Institute of Oceanography, Goa, 1987)
      A method to add zeros (in FFT methods) to a short data sample (< 2m) to make the sample size equal to 2m is illustrated in this paper. It is found that the spectrum could be computed reliably without any undesirable side ...
