Analogue phase and frequency synchronizer for data communications

Claim 1

A PULSE COMMUNICATION SYNCHRONIZER FOR A BINARY DATA TRAIN OF PULSES HAVING DETECTABLE TRANSITIONS BETWEEN BINARY STATES COMPRISING AN OSCILLATOR FOR GENERATING A TIMING WAVEFORM, MEANS RESPONSIVE TO SAID TRANSITIONS AND SAID WAVEFORM TO OBTAIN AN ANLOGUE QUANTITY REPRESENTATIVE OF THE PHASE ERROR THEREBETWEEN FOR ALTERING THE INDIVIDUAL PERIODS OF SAID WAVEFORM IN MAGNITUDE AND SENSE TO POSITION A REFERENCE POINT WITHIN SAID PERIODS CLOSER TO SAID TRANSITIONS, MEANS FOR INTEGRATING SAID ANALOGUE QUANTITY TO OBTAIN A SECOND QUANTITY REPRESENTING THE AVERAGE DIFFERENCE BETWEEN THE TIME OF SAID TRANSITIONS AND SAID REFERENCE POINT TO CONTROL THE FREQUENCY OF SAID OSCILLATOR AND REDUCE SAID AVERAGE DIFFERENCE TO A MINIMUM, AND MEANS FOR DERIVING AN OUTPUT WAVE SYNCHRONIZED WITH SAID TIMING WAVEFORM.
