Claim 1
Independent Claim
123 words
A COMMUNICATIONS SYNCHRONIZER FOR RECEIVED BINARY SIGNALS COMPRISING A FIRST HIGH-Q ELECTROMECHANICALLY STABILIZED OSCILLATOR HAVING A FREQUENCY ADJUSTABLE WITHIN NARROW LIMITS CORRESPONDING TO THE BIT RATE OF SAID SIGNALS, A SECOND OSCILLATOR TRIGGERED TO OSCILLATE IN ACCORDANCE WITH THE FREQUENCY OF SAID FIRST OSCILLATOR AND WITH ADJUSTABLE PHASE RELATIVE TO SAID FIRST OSCILLATOR, MEANS RESPONSIVE TO THE OUTPUT OF SAID SECOND OSCILLATOR AND RECEIVED BINARY SIGNALS FOR ALTERING THE PHASE OF SAID SECOND OSCILLATOR TO MAINTAIN A PREDETERMINED PHASE RELATION BETWEEN SAID OUTPUT AND SAID BINARY SIGNALS, MEANS RESPONSIVE TO SUSTAINED DEVIATION FROM SAID PREDETERMINED PHASE RELATION FOR CHANGING THE FREQUENCY OF SAID FIRST OSCILLATOR TO CORRESPOND TO SAID BIT RATE, AND MEANS FOR OBTAINING A SYNCHRONIZING SIGNALS OUTPUT FROM SAID SECOND OSCILLATOR.
