Pulse train checking circuit
Abstract
Abstract AN ARRANGEMENT FOR CHECKING THAT SPECIFIED MINIMA ARE MET BY THE PULSE, INTERPULSE AND PULSE REPETITION PERIODS OF A PULSE TRAIN, INCLUDING FIRST AND SECOND TIMING CIRCUITS NORMALLY OPERATIVE DURING THE INTERPULSE AND PULSE PERIODS RESPECTIVELY, FOR DEFINING TIMING INTERVALS CORRESPONDING TO THE RESPECTIVE MINIMA SPECIFIED THEREFOR. UPON A SATISFACTORY CHECK OF THE INTERPULSE PERIOD, THE FIRST TIMING CIRCUIT OPERATES FOR A PREDETERMINED PERIOD CORRESPONDING TO THE DIFFERENCE BETWEEN THE SPECIFIED REPETITION PERIOD MINIUM AND THE SUM OF THE PULSE AND INTERPULSE MINIMA TO INHIBIT THE OPERATION OF THE SECOND TIMING CIRCUIT. THE LATTER PROVIDES AN OUTPUT SIGNAL ONLY IF IT "TIMES OUT" BEFORE THE PULSE PERIOD HAS TERMINATED, THEREBY INDICATING THAT ALL THREE MINIMA HAVE BEEN MET.
