Pulse rate to amplitude converter

Claim 1

IN A RATE-TO-AMPLITUDE CONVERTER, A CONSTANT AREA PULSE GENERATOR COMPRISING A SYNCHRONIZER, MEANS FOR APPLYING AN INPUT SIGNAL HAVING AN INPUT PULSE RATE TO SAID SYNCHRONIZER, SAID SYNCHRONIZER BEING ADAPTED TO BE SET BY SAID INPUT PULSES, MEANS FOR PERIODICALLY APPLYING FIRST TIMING PULSES TO SAID SYNCHRONIZER, SAID SYNCHRONIZER IN ITS SET STATE BEING ADAPTED TO BE RESET BY SAID TIMING PULSES TO PROVIDE OUTPUT PULSES, A FLIP FLOP CIRCUIT, MEANS COUPLING SAID OUTPUT PULSES TO SAID FLIP-FLOP CIRCUIT TO CAUSE SAID FLIP-FLOP CIRCUIT TO BE SET BY SAID OUTPUT PULSES, MEANS FOR PERIODICALLY APPLYING SECOND TIMING PULSES TO SAID FLIP-FLOP CIRCUIT, EACH OF SAID SECOND TIMING PULSES OCCURRING A PREDETERMINED TIME PERIOD AFTER THE CORRESPONDING FIRST TIMING PULSE, SAID FLIP-FLOP CIRCUIT BEING ADAPTED TO BE RESET BY SAID SECOND TIMING PULSES TO PROVIDE CONSTANT WIDTH OUTPUT PULSES, MEANS FOR AMPLITUDE LIMITING SAID LAST RECITED PULSES TO PROVIDE A CONSTANT AREA PULSE SIGNAL, AN AVERAGING CIRCUIT, AND MEANS FOR APPLYING SAID LAST RECITED SIGNAL TO SAID AVERAGING CIRCUIT TO PROVIDE A DIRECT CURRENT SIGNAL VARYING AS A FUNCTION OF THE INPUT RATE.
