Abstract :
Parametric subharmonic oscillators are already used as elementary circuits for digital computers. It is shown that a theory exists, which, by purely algebraic procedures, gives a reasonable account of the steady-state oscillations of these systems. The concepts used belong to linear circuit theory. The stability is studied for each solution, by treating small perturbations also by linear methods. This is possible with a good approximation only in case the circuit is sufficiently selective. A few diagrams are drawn to show the agreement between the theoretical model considered here and actual circuits studied by others.
