A model of a pulse phase-locked loop multiplying ring in a MicroCap11 medium is considered. The analysis uses a nonlinear model of a voltage-controlled oscillator with a user-defined control characteristic. An RS-trigger is used as a pulse-phase detector, a pulse counter in the negative feedback circuit is implemented on JK-triggers. Transient processes in the ring, as well as the spectrum of the output oscillations in the steady (stationary) mode are considered.
