The amplitude of the Fourier components as a function of frequency is shown. The amplitude first decays, then reaches a plateau, and then decays again. Both even and odd harmonics exist. The model parameters used to produce this spectrum are ω = 1 = 10ω0, v3 = 1, \({v}_{4}=\frac{1}{2}\), Γ = 10, and F(t) = 0.5sin (ω0t).
