Typical hierarchy of pulsing solutions obtained with increasing excitation parameter and corresponding frequency spectra. (a) Symmetric solution with period one, obtained with 2 𝐶 = 1 8 . 4 , (b) asymmetric period one solution, obtained with 2 𝐶 = 2 7 . 9 , (c) asymmetric solution with period two, obtained with 2 𝐶 = 2 9 . 5 , (d) frequency spectrum of the period one solution, (e) frequency spectrum of the asymmetric solution, showing the emergence of small even harmonics, and (f) frequency spectrum of the asymmetric period two solution, where, in addition to the even harmonics of (e), additional peaks appear at intermediate values between the odd and even components (subharmonic components).
