Clampers are electronic circuit which are used to change the position of the peak of a ac signal waveform to a new level.It is applicable for both the positive and negative peaks.The main components of a clamper circuit are diode and capacitor.
Clampers are of two types: (1). Positive Clamper (2). Negative Clamper
This video explains about the basic concepts of clampers,classification,circuit design,operation and input-output waveforms of clamper circuits.
