This value depended on the forcing frequency and the equivalence ratio.
The technique does not put constraints on the forcing, which could be arbitrary, e.g., white noise or other stochastic variants.

The paper shows that this identification problem can be circumvented by reverse-engineering the cross-equation restrictions on the forcing variable of the Euler equation.
We conduct an experimental study on the forcing functions generated by a vibrodyne, and the mismatches between such loading histories and the theoretical sinusoidal profiles.
In this case the amplitude only depends on the time it takes for the system to change sign and on the forcing amplitude.
Our analysis explains the lower bound on wavelength, or the upper bound on the forcing frequency, of naturally and artificially excited interfacial patterns.
It was found that depending on the forcing conditions and the geometric/viscous characteristics of the system, various pairs of gear teeth could be excited, exhibiting a different system response.
