Q1: The primary function of a clamper circuit is to

A suppress variations in signal voltage

B raise +ve half cycle to the signal

C Lower -ve half cycle of the signal

D introduce a dc level into an a.c. signal

ANS:B - raise +ve half cycle to the signal

A clamper is a network of a diode, a resistor, and a capacitor that shifts a waveform to a different dc level without changing the appearance of the applied signal.
