Synchronous oscillation of parametric generators is analyzed on the basis of the method of slowly varying amplitudes for the case in which the nonlinear element is turned on repeatedly over a period of the subharmonic oscillations. When the nonlinear element is turned on repeatedly, the bands of Internal self-synchronization and division decrease with increasing value of n, the self-synchronization order, more rapidly (~ 1/n^3/^2), than In the case in which the nonlinear element is turned on only once (~l/n). The decrease is nevertheless weaker than the decrease in the bands upon the formation of combination frequencies at a gradual nonlinearity.
