Right Answer is: A
SOLUTION
- An analog comparator has two inputs. One is a constant reference voltage VR and the other is time-varying signal Vi and one output Vo.
- When the non-inverting voltage is larger than the inverting voltage the comparator produces a high output voltage (+Vsat).
- When the non-inverting voltage is less than the inverting voltage the comparator produces a low output voltage (-Vsat).
