18. 2 on the left-hand side. For a certain set of model parameters we observe again a low-dimensional chaotic flow which can be controlled using the technique described above for a first-order model. Now, however, the phase of the signal changes more sporadically. This results in a much smaller carrier power (11% of the total signal power as compared to 70% for the first order model) and, therefore, higher power efficiency.
