Sampled reentrant data processing system

Claim 1

A RE-ENTRANT DATA PROCESSING SYSTEM COMPRISING A SIGNAL DELAY MEANS HAVING A DELAY TIME D, AMPLIFIER MEANS, A FIRST GATE CIRCUIT, A SIGNAL ADDER MEANS, AND MEANS COUPLING SAID ABOVE RECITED ELEMENTS IN A CLOSED SIGNAL LOOP, SAID CLOSED SIGNAL LOOP INCLUDING MEANS PROVIDING AN ADDITIONAL SIGNAL DELAY TIME D, WHEREBY THE SIGNAL PROPAGATION TIMES AND AROUND SAID CLOSED LOOP IS EQUAL TO D+D, SAID SIGNAL ADDER MEANS HAVING FIRST AND SECOND INPUTS AND A COMMON OUTPUT, SAID FIRST INPUT BEING COUPLED TO THE OUTPUT OF SAID SECOND INPUT OF SAID ADDER GATE CIRCUIT COUPLED TO SAID SECOND INPUT OF SAID ADDER MEANS, MEANS FOR SUPPLYING SIGNALS TO BE PROCESSED TO SAID SECOND GATE CIRCUIT, MEANS COUPLED TO SAID SECOND GATE CIRCUIT FOR RENDERING SAID GATE CIRCUIT OPERATIVE TO PASS SIGNALS TO SAID SECOND INPUT OF SAID ADDER MEANS ONLY DURING TIME INTERVALS OF DURATION Y, SAID INTERVALS OF DURATION Y HAVING A RECURRENCE PERIOD R, WHERE NR=D,N BEING AN INTEGER, AND Y IS NOT GREATE THAN D, AND MEANS COUPLED TO SAID FIRST GATE CIRCUIT FOR RENDERING SAID FIRST GATE CIRCUIT INOPERATIVE TO PASS SIGNALS FOR SAID TIME INTERVALS OF DURATION Y DURING WHICH SAID SECOND GATE CIRCUIT IS OPERATIVE TO PASS SIGNALS.
