Abstract : 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)
