A discrete wave displacement time-series record is usually analyzed by a Discrete Fourier Transform (DFT), which represents the record as the sum of a finite number of harmonic sinusoids. When the dominant sinusoid of the record is not one of these harmonics, DFT "leakage" produces a distorted pictu
