The amplitude q-sub-0 = 200. As is evident from Figs. 4a–4d, all characteristics [(a) signal, (b) power spectrum, (c) phase portrait, and (d) the Poincare section] refer to vibrations that occur at the same frequency, namely, the excitation frequency ω-sub-p
The surface of the Morlet wavelet (Fig. 4f) and its projection on the plane (Fig. 4e) also show vibrations at the same frequency practically over the whole time interval.
