Explanation: The output resistance of the circuit is non-uniform as it depends on the state of diode. That is, the output impedance is low when diode is on and high when diode is off. 12. A circuit with a predetermined dc level is added to the output voltage of the op-amp is called
A. Clamper
B. Positive clipper
C. Halfwave rectifier
D. None of the mentioned
