THEORY:
The diode clipper, also known as a diode limiter, is a wave shaping circuit that limits positive or negative amplitude, or both. In electronics, diode clipper circuits are commonly used to process various signals. It is is a circuit designed to prevent a signal from exceeding a predetermined reference voltage level. Clipping changes the shape of the waveform and alters its spectral components.
The clamper circuits are also called DC restorers. These circuits are especially used to shift the applied waveforms to above or below levels of the DC reference voltage without showing the impact on the shape of the waveform. This shifting tends to modify the Vdc level of the applied wave.

Questions with answers:
1. Define rectifier
Rectifier is an electronic device which converts Alternating Current (AC) to Direct Current (DC) by allowing electric current to flow through it in only one direction.
2. DC stands for –
Direct Current
