APPROPRIATE TO GENERATE A SIGNAL OF DIVISION FATHER CONTROL, GENERAL CIRCUIT OF LIFT SELECTION FATHER SELECTION, AND PROCESS TO REGULATE THE OPERATION OF A VC WHICH GENERATES A VCO HEALTH SIGNAL AND FORMS A PLL CIRCUIT PORCUIT" A modulator circuit It sym 30 30;and an associated process generates a frequency regulated signal (26) that does not have undesirable tones. Wobble signals (46) are generated and are provided to a sym30 modulator (38). The sym30 modulator (38) forms a division factor control signal (36) used to control the division factor of a frequency divider (28) forming a portion of the PLL circuit (12). Wobbling signals 46 applied to the sym30 modulator 38 reduce the likelihood that the sym30 modulator 38 enters a limit loop and generates repetitive output signals.
