D. None of the mentioned
Answer:A
In which configuration a dead band condition occurs in schmitt trigger
A. Differential amplifier with positive feedback B. Voltage follower with positive feedback C. Comparator with positive feedback D. None of the mentioned
Explanation: The comparator with positive feedback is said to exhibit hysteresis, a dead band condition, when the input of comparator exceeds upper threshold voltage. At this condition, output switch from +Vsat to -Vsat. It reverts back to its original state, +Vsat when the input goes below lower threshold voltage. 6. Calculate the hysteresis voltage for the schmitt trigger from the given specification:
