If the period duration is lesser than 400 ms, the one-shot will deliver a pulse.(a) True(b) FalseI had been asked this question during an online interview.The origin of the question is Recording System in division Foetal Monitoring Instruments of Biomedical Instrumentation

Answer»

Correct choice is (b) False

The best explanation: False, to detect the HEART frequency, the 400 ms one-shot is used. If the period duration is greater than 400 ms, the one-shot will deliver a pulse. The NEGATIVE SLOPE of this pulse is used to trigger the 20 ms one-shot. These 20 ms PULSES are integrated by the integrator and the OUTPUT of this integrator is compared with a fixed voltage -V.
