Claim 1
Independent Claim
189 words
IN A REDUNDANT SIGNAL TRANSMISSION CHANNEL, THE COMBINATION COMPRISING A SIGNAL TRANSMISSION PATH HAVING AN INPUT AND AN OUTPUT, A FURTHER SIGNAL TRANSMISSION PATH HAVING AN INPUT AND AN OUTPUT, COMMON INPUT MEANS FOR SAID PATHS HAVING AN INPUT SIGNAL IMPRESSED THEREON, MEANS FOR SPLITTING SAID INPUT SIGNALS INTO TWO IN-PHASE COMPONENTS THE SUM OF WHICH IS EQUAL TO SAID INPUT SIGNAL, SAID SIGNAL COMPONENTS BEING INDIVIDUALLY AND SIMULTANEOUSLY TRANSMITTED OVER SAID PATHS, SAID PATHS EACH INCLUDING AN ACTIVE DEVICE WHICH CONTROLS THE AMPLITUDE RESPONSE OF SAID PATH, COMMON OUTPUT SUMMING MEANS COUPLED TO THE OUTPUT OF SAID PATHS FOR SERIALLY RECOMBINING THE SIGNAL THE MAGNITUDE OF WHICH IS THE SUM OF THE TRANSMITTED COMPONENTS, AND MEANS FOR COUPLING THE OUTPUT OF ONE OF THE SAID ACTIVE DEVICES TO THE INPUT OF THE REMAINING DEVICE AND THE OUTPUT OF THE REMAINING DEVICE TO THE INPUT OF SAID ONE DEVICE TO CONTROL CONTINUOUSLY THE TRANSMISSION CHARACTERISTICS OF EACH PATH IN RESPONSE TO THE SIGNAL LEVEL IN THE OTHER PATH WHEREBY FAILURE OR DETERIORATION OF SIGNAL TRANSMISSION IN ONE OF SAID PATHS DOES NOT AFFECT THE AMPLITUDE OF THE RECOMBINED SIGNAL.
