A. Monostable multivibrator B. Astable multivibrator C. Schmitt trigger D. None of the mentioned
Explanation: A monostable multivibrator can be used as a missing pulse detector by connecting a transistor between trigger inputs. If a pulse misses, the discharge trigger input goes high & transistor become cut-off and the output goes low. So, this type of circuit can be used to detect missing heart beat. 6. A 555 timer in monostable application mode can be used for
