Correct option is D
A clamper circuit is used to shift the entire waveform up or down along the voltage axis, effectively adding or subtracting a DC component to/from the signal.
Key Function of a Clamper:
· Inserts a DC value into an AC signal without altering the shape of the waveform.
· It does not clip or limit peaks; it only shifts the waveform.
· For example, a negative clamper shifts the entire waveform upwards so that the negative peaks touch zero voltage.
