Asynchronous quenching AQ is a type of asynchronous action that consists essentially in quenching a self-sustained soft oscillation by imposing an externally produced high-frequency perturbation on the oscillator. Minorsky treats this subject in his book, Nonlinear Oscillations, by using the stroboscopic method. Although this leads to a correct result the self-sustained oscillation is quenched, there is a misleading aspect of the mathematical statement which tends to make the unwary reader jump to the conclusion that very high-frequency perturbations can quench an oscillation, leaving behind only a DC solution. As will be shown, this is false, and AQ turns out to be nothing other than harmonic entrainment at large detuning. Author
