Abstract

1331432 Detecting pulse signals BRITISH AIRCRAFT CORP Ltd 22 Oct 1970 [22 Oct 1969] 51798/69 Heading G1U [Also in Divisions G4 H2 and H3] A monitoring circuit for detecting the failure of either one of a pair of pulse generators 1, 3 and 2, 4 comprises a bi-stable circuit 9 having first and second inputs connected to receive pulses from the generators 1, 3, and 2, 4 respectively such that pulses from one generator trigger the bi-stable 9 from one level to the other and the pulses from the other generator trigger the bi-stable to return the output to the original level, an integrator 10 responsive to the output of the bi-stable circuit 9 and an indicator 12 responsive to the output of the integrator whereby the indicator is energized only when both pulse generators are producing pulses.
