Claim 1

A SYSTEM FOR PROPAGATING A PLURALITY OF AMPLITUDE VARYING SIGNALS EACH INDICATIVE OF A DISTINCT INTELLIGENCE, SAID SYSTEM COMPRISING: (A) A PLURALITY OF MEANS EACH RESPONSIVE TO A RESPECTIVE ONE OF SAID PLURALITY OF SIGNALS TO PRODUCE A TRAIN OF VOLTAGE PULSES WHOSE REPETITION RATE VARIES AS A FUNCTION OF THE AMPLITUDE OF THE SIGNAL APPLIED THERETO AND WHOSE AMPLITUDE HAS A PREDETERMINED CONSTANT LEVEL WHICH DIFFERS FROM THE LEVEL OF THE VOLTAGE PULSE TRAINS DERIVED FROM THE OTHER SIGNALS, (B) A NORMALLY QUIESCENT FREQUENCY-MODULATED CARRIER OSCILLATOR WHOSE OUTPUT FREQUENCY, WHEN THE OSCILLATOR IS OPERATIVE, DEPENDS ON THE AMPLITUDE OF AN INPUT VOLTAGE PULSE APPLIED THERETO, (C) A PULSE-RESPONSIVE CONTROL DEVICE COUPLED TO SAID OSCILLATOR TO RENDER IT OPERATIVE ONLY WHEN AN INPUT VOLTAGE PULSE IS APPLIED TO SAID DEVICE, (D) MEANS TO APPLY THE VOLTAGE PULSES IN EACH TRAIN THEREOF BOTH TO SAID DEVICE AND TO SAID OSCILLATOR TO RENDER SAID OSCILLATOR OPERATIVE TO PRODUCE FOR EACH VOLTAGE PULSE APPLIED TO SAID DEVICE AN OUTPUT CARRIER WHOSE FREQUENCY DEPENDS ON THE AMPLITUDE OF THE SAME VOLTAGE PULSE, WHEREBY SAID OSCILLATOR YIELDS FOR EACH APPLIED TRAIN OF VOLTAGE PULSES A CORRESPONDING TRAIN OF CARRIER PULSES HAVING A DISTINCT FREQUENCY, AND (E) RECEIVER MEANS TO INTERCEPT THE TRAINS OF CARRIER PULSES AND INCLUDING SELECTIVE CIRCUITS TO SEPARATE THE TRAINS OF CARRIER PULSES FROM EACH OTHER AND DEMODULATION CIRCUITS COUPLEDL TO SAID SELECTIVE CIRCUITS TO DEMODULATE EACH OF SAID TRAINS OF CARRIER PULSES, THEREBY TO RECOVER SAID AMPLITUDE VARYING SIGNALS.

Claim 2

A SYSTEM FOR PROPAGATING A PLURALITY OF AMPLITUDE VARYING SIGNALS EACH INDICATIVE OF A DISTINCT INTELLIGENCE, SAID SYSTEM COMPRISING: (A) A PLURALITY OF MEANS EACH RESPONSIVE TO A RESPECTIVE ONE OF SAID PLURALITY OF SIGNALS TO PRODUCE A TRAIN OF VOLTAGE PULSES WHOSE REPETITION RATE VARIES AS A FUNCTION OF THE AMPLITUDE OF THE SIGNAL APPLIED THERETO AND WHOSE AMPLITUDE HAS A PREDETERMINED CONSTANT LEVEL WHICH DIFFERS FROM THE LEVEL OF THE VOLTAGE PULSE TRAINS DERIVED FROM THE OTHER SIGNALS, (B) A NORMALLY QUIESCENT FREQUENCY-MODULATED CARRIER OSCILLATOR WHOSE OUTPUT FREQUENCY, WHEN THE OSCILLATOR IS OPERATIVE, DEPENDS ON THE AMPLITUDE OF AN INPUT VOLTAGE PULSE APPLIED THERETO, (C) A PULSE-RESPONSIVE CONTROL DEVICE COUPLED TO SAID OSCILLATOR TO RENDER IT OPERATIVE ONLY WHEN AN INPUT VOLTAGE PULSE IS APPLIED TO SAID DEVICE, (D) MEANS TO APPLY THE VOLTAGE PULSES IN EACH TRAIN THEREOF BOTH TO SAID DEVICE AND TO SAID OSCILLATOR TO RENDER SAID OSCILLATOR OPERATIVE TO PRODUCE FOR EACH VOLTAGE PULSE APPLIED TO SAID DEVICE AN OUTPUT CARRIER WHOSE FREQUENCY DEPENDS ON THE AMPLITUDE OF THE SAME VOLTAGE PULSE, WHEREBY SAID OSCILLATOR YIELDS FOR EACH APPLIED TRAIN OF VOLTAGE PULSES A CORRESPONDING TRAIN OF CARRIER PULSES HAVING A DISTINCT FREQUENCY, AND (E) RECEIVER MEANS TO INTERCEPT THE TRAINS OF CARRIER PULSES AND INCLUDING SELECTIVE CIRCUITS TO SEPARATE THE TRAINS OF CARRIER PULSES FROM EACH OTHER AND DEMODULATION CIRCUITS COUPLEDL TO SAID SELECTIVE CIRCUITS TO DEMODULATE EACH OF SAID TRAINS OF CARRIER PULSES, THEREBY TO RECOVER SAID AMPLITUDE VARYING SIGNALS.
