Abstract
A digital transmission system including synchronizing circuits for estimating and compensating for errors between a local oscillator signal and an input signal. The synchronizing circuits include a phase/frequency detector and correction circuit for correcting errors in an unlocked mode, and a phase detection and correction circuit for correcting errors in a locked mode. Requests for changing the synchronization circuits from the locked mode to the unlocked mode are implemented by state control circuits only after application of at least one decision condition. The state control circuits may also save and restore specific adjustments responsive to the decision condition.
