Frequency control of oscillators
Abstract
Abstract A MEANS FOR CONTROLLING THE OPERATING FREQUENCIES OF AN INTERCONNECTED SYSTEM OF OSCILLATORS. FREQUENCY CONTROL OF EACH OSCILLATOR IS EFFECTED BY APPLICATION OF D.C. SIGNALS DERIVED FROM COMPARISON BETWEEN THE OPERATING FREQUENCIES OF THE OSCIALLATOR CONCERNED AND THE RESPECTIVE OSCILLATORS TO WHICH IT IS DIRECTLY CONNECTED. THE COMPARISON IS USED TO PRODUCE D.C. ERROR SIGNALS FROM WHICH THE D.C. FREQUENCY SHIFTING SIGNAL IS DERIVED, THE LATTER HAVING A MAGNITUDE DEPENDENT ON THE ALGEBRAIC SUM OF THE ERROR SIGNALS DIVIDED BY A FACTOR DEPENDENT ON THE NUMBER OF OTHER OSCILLATORS TO WHICH THE OSCILLATOR CONCERNED IS DIRECTLY CONNECTED. THUS, THE DEGREE OF CONTROL EXERCISED ON THE SYSTEM BY ANY PARTICULAR OSCILLATOR INCREASES WITH THE NUMBER OF CONNECTIONS BETWEEN THAT OSCILLATOR AND OTHER OSCILLATORS IN THE SYSTEM. THE INVENTION IS DESCRIBED WITH REFERENCE TO A P.C.M. COMMUNICATIONS SYSTEM AND HAS OTHER APPLICATIONS.
