No output pulse will occur when the period between two pulses is less than _____ ms.(a) 230(b) 20(c) 400(d) 440The question was posed to me during an interview for a job.Asked question is from Recording System topic in division Foetal Monitoring Instruments of Biomedical Instrumentation

Answer»

The correct ANSWER is (c) 400

To elaborate: No output PULSE will occur if the period between TWO pulses is LESS than 400 MS. The 20 ms pulses are, therefore, not generated and the integrator discharges slowly from the negative output voltage to a positive output voltage. If the output of the integrator (6) is less negative than-V, the output of the comparator (7) will become negative.
