An exact analysis of a parametric subharmonic oscillator

An analysis of a subharmonic oscillator using an ideal nonlinear capacitor is given in which the variables are so chosen that the problem reduces to a set of linear equations. The resulting solutions are exact, but multivalued, and the choice of the correct one is made as a result of experiments using a step-recovery diode. The method of analysis should be applicable to a wider range of piecewise-linear problems.
