A system for synchronizing a freely-oscillating signal to a reference oscillator which generates a subharmonic of the final desired frequency, wherein the free running oscillator has its output coupled to a phase discriminator and the reference oscillator is also supplied to the phase discriminator after conversion into pulses, with the output of the phase discriminator being coupled to an amplifier and hence to a control terminal of the free running oscillator for locking that oscillator to the desired frequency. |
