  • Precision phase synchronization of free-running oscillator output signal to reference signal
    Patent number: 4600895
    Abstract: A synchronization circuit for a free-running oscillator, in which a multi-tapped delay line provides delayed outputs incrementally spaced throughout the period and at the same frequency as the oscillator.
