Phase modulation system for reading particular information

Claim 1

IN COMBINATION WITH A SYSTEM WHEREIN INFORMATION IS CONVERTED INTO A SERIES OF PULSE SIGNALS INCLUDING EQUALLY SPACED SIGNIFICANT PULSES REPRESENTING INFORMATION AND NON-SIGNIFICANT PULSES, THE TIME BETWEEN CONSECUTIVE SIGINIFICANT PULSES BEING EQUAL TO ONE FULL SIGNAL PERIOD, A TRIGGERABLE DELAY FLOP CIRCUIT FOR PRODUCING AN INHIBIT SIGNAL ADAPTED TO BE TRIGGERED BY A PLUSE SIGNAL, SAID INHIBIT SIGNAL BEING OF A DURATION MORE THAN ONE HALF AND LESS THAN A FULL SIGNAL PERIOD, MEANS FOR APPLYING SAID SERIES OF PULSE SIGNALS TO SAID DELAY FLOP CIRCUIT, A FIRST MEANS FOR INHIBITING SAID NON-SIGNIFICANT PULSES FOR A PREDETERMINED TIMED PERIOD WHEREBY SAID DELAY FLOP CIRCUIT IS TRIGGERED BY THE PULSES REPRESENTING SAID SIGNIFICANT SIGNALS, AND MEANS FOR APPLYING SAID INHIBIT SIGNAL FROM SAID FLOP CIRCUIT TO INHIBIT SAID NON-SIGNIFICANT PULSES.
