Explanation: When 555 timer is configured in monostable operation, the trigger input is applied through pin2 whereas, upper comparator threshold (pin6) & discharge (pin7) are shorted and connected at the output. 3. How to overcome mistriggering on the positive pulse edges in the monostable circuit?
A. Connect a RC network at the input
B. Connect an integrator at the input
C. Connect a differentiator at the input
D. Connect a diode at the input
Answer:A

A. Connect a RC network at the input B. Connect an integrator at the input C. Connect a differentiator at the input D. Connect a diode at the input
Explanation: To prevent the mistrigger on positive pulse edges, a resister & capacitor combined of 10kΩ and 0.001µF at the input to form a differentiator
