Method and system for central station generation and transmission of radio carrier waves for use by remote modulating and transmitting stations

Claim 1

A SYSTEM FOR RADIO SIGNAL TRANSMISSION COMPRISING: A CENTRAL STATION HAVING MEANS FOR GENERATING THE CARRIER WAVES FOR THE ASSIGNED FREQUENCIES OF PLURAL REMOTE RADIO STATIONS, SAID CENTRAL STATION ALSO HAVING A BROAD BAND TRANSMITTING MEANS FOR AMPLIFYING AND TRANSMITTING SAID PLURAL CARRIER WAVES, REMOTELY LOCATED RADIO STATIONS HAVING MEANS FOR RECEIVING CARRIER WAVES TRANSMITTED FROM SAID CENTRAL STATION, EACH STATION BEING ASSIGNED A SPECIFIC CARRIER FREQUENCY ON WHCIH IT OPERATES WHICH IS SEPARATED IN FREQUENCY FROM THE CARRIER FREQUNCY ASSIGNED TO OTHER REMOTE STATIONS RECEIVING CARRIER WAVES FROM SAID CENTRAL STATION, EACH REMOTE STATION FURTHER HAVING A SELECTIVE CARERIER WAVE SIGNAL DISCRIMINATING MEANS FOR PASSING ONLY THE CARRIER WAVE FREQUENCY ASSIGNED TO THE REMOTE STATION, A RADIO PROGRAM ORIGINATING MEANS FOR PRODUCING MODULATION SIGNALS, A MODULATOR FOR MODULATING A SELECTED CARRIER WAVE WITH MODULATION SIGNALS, AND TRANSMITTING MEANS FOR TRANSMITTING THE MODULATED CARRIER WAVES TO REMOTE RADIO RECEIVING SETS, SAID MEANS FOR GENERATING THE CARRIER WAVES FOR THE ASSIGNED FREQUENCIES OF PLURAL REMOTE STATIONS COMPRISING PLURAL SIGNAL GENERATORS EACH OPERATING ON A SEPARATE ONE OF THE ASSIGNED FREQUENCIES, AND SWITCHING MEANS FOR SELECTIVELY CONNECTING EACH SIGNAL GENERATOR TO SAID BROAD BAND TRANSMITTING MEANS, AND SAID SELECTIVE CARRIER WAVE SIGNAL DISCRIMINATING MEANS FOR PASSING ONLY THE CARRIER WAVE FREQUENCY ASSIGNED TO THE REMOTE STATION INCLUDING A SELECTIVE FREQUENCY FILTER IN SERIES CIRCUIT WITH AN AMPLIFIER HAVING SIGNAL INPUT AND OUTPUT TERMINALS, AND A DEGENERATIVE FEED BACK CIRCUIT CONNECTED FROM THE SIGNAL OUTPUT TERMINAL OF SAID AMPLIFIER TO THE SIGNAL INPUT TERMINAL OF SAID AMPLIFIER, SAID FEED BACK CIRCUIT FEEDING BACK SIGNALS OF OTHER THAN THE CARRIER WAVE FREQUENCY ASSIGNED TO THE REMOTE STATION FROM THE OUTPUT OF SAID AMPLIFIER IN PHASE OPPOSITION TO SIGNALS COMING INTO SAID INPUT FROM SAID SELECTIVE FREQUENCY FILTER.

Claim 2

A SYSTEM FOR RADIO SIGNAL TRANSMISSION COMPRISING: A CENTRAL STATION HAVING MEANS FOR GENERATING THE CARRIER WAVES FOR THE ASSIGNED FREQUENCIES OF PLURAL REMOTE RADIO STATIONS, SAID CENTRAL STATION ALSO HAVING A BROAD BAND TRANSMITTING MEANS FOR AMPLIFYING AND TRANSMITTING SAID PLURAL CARRIER WAVES, REMOTELY LOCATED RADIO STATIONS HAVING MEANS FOR RECEIVING CARRIER WAVES TRANSMITTED FROM SAID CENTRAL STATION, EACH STATION BEING ASSIGNED A SPECIFIC CARRIER FREQUENCY ON WHCIH IT OPERATES WHICH IS SEPARATED IN FREQUENCY FROM THE CARRIER FREQUNCY ASSIGNED TO OTHER REMOTE STATIONS RECEIVING CARRIER WAVES FROM SAID CENTRAL STATION, EACH REMOTE STATION FURTHER HAVING A SELECTIVE CARERIER WAVE SIGNAL DISCRIMINATING MEANS FOR PASSING ONLY THE CARRIER WAVE FREQUENCY ASSIGNED TO THE REMOTE STATION, A RADIO PROGRAM ORIGINATING MEANS FOR PRODUCING MODULATION SIGNALS, A MODULATOR FOR MODULATING A SELECTED CARRIER WAVE WITH MODULATION SIGNALS, AND TRANSMITTING MEANS FOR TRANSMITTING THE MODULATED CARRIER WAVES TO REMOTE RADIO RECEIVING SETS, SAID MEANS FOR GENERATING THE CARRIER WAVES FOR THE ASSIGNED FREQUENCIES OF PLURAL REMOTE STATIONS COMPRISING PLURAL SIGNAL GENERATORS EACH OPERATING ON A SEPARATE ONE OF THE ASSIGNED FREQUENCIES, AND SWITCHING MEANS FOR SELECTIVELY CONNECTING EACH SIGNAL GENERATOR TO SAID BROAD BAND TRANSMITTING MEANS, AND SAID SELECTIVE CARRIER WAVE SIGNAL DISCRIMINATING MEANS FOR PASSING ONLY THE CARRIER WAVE FREQUENCY ASSIGNED TO THE REMOTE STATION INCLUDING A SELECTIVE FREQUENCY FILTER IN SERIES CIRCUIT WITH AN AMPLIFIER HAVING SIGNAL INPUT AND OUTPUT TERMINALS, AND A DEGENERATIVE FEED BACK CIRCUIT CONNECTED FROM THE SIGNAL OUTPUT TERMINAL OF SAID AMPLIFIER TO THE SIGNAL INPUT TERMINAL OF SAID AMPLIFIER, SAID FEED BACK CIRCUIT FEEDING BACK SIGNALS OF OTHER THAN THE CARRIER WAVE FREQUENCY ASSIGNED TO THE REMOTE STATION FROM THE OUTPUT OF SAID AMPLIFIER IN PHASE OPPOSITION TO SIGNALS COMING INTO SAID INPUT FROM SAID SELECTIVE FREQUENCY FILTER.
