1.What is meant by clippers?
Clippers is a circuit in which the waveform is shaped by removing certain portion of the input signal voltage above or below a certain level. The PN junction diode is an extremely useful device in non-linear wave shaping circuit such circuit are used to perform function of amplitude emitting, clipping and clapping.
2.Give the application of clipper
• Digital computer
• Radars
• Radio and television receivers
• To emit the amplitude of the input signal voltage
3.What is meant by clamper?
The circuit which the waveform can be shifted in such a way so that a particular part (positive or negative peak) is maintained at a specified voltage level is called a clamping circuit or clampers.It restores DC level to an AC signal. So it is also know as DC restore. It used in TV receiver to restore the original DC reference to video signal.
