Fourier coefficients for the first four strongest frequencies in Fourier spectrum.

The Fourier amplitudes for sulpa mouse #18 shown in Fig 14 for the 100 trials with three Fourier coefficients (the second and third columns), five coefficients (the fourth and fifth columns), and 10 coefficients (the sixth and seventh columns). The first column represents the integer frequency index k. Although each trial was synthesized using the largest 3, 5, or 10 Fourier amplitudes, different trials have different combinations of frequencies. For each of the three decompositions in Fourier components, we show what fraction of the trials required a particular frequency.
