Abstract : The patent describes a synchronization system having a plurality of control loops operative together to optimize the rate of frequency acquisition and synchronization. A first loop acquires the frequency of the unknown signal. A coarse phase-lock loop then adjusts the system to provide a phase-error signal. A fine phase-lock loop then makes the final adjustments to the system. As each step in the synchronization sequence is achieved, the circuitry which is no longer needed is switched out of operation.
