Abstract
A phase-lock circuit for controlling an oscillator includes a sampling gate that operates during a gate interval to pass transitions in a comparison signal derived from the oscillator to produce therefrom an oscillator-controlling error signal that is representative of the phase-error direction and magnitude of the substantially symmetrical relationship between occurrence of transitions in the comparison signal within the interval of the gate pulse.
