Q. Write a note on clampers ?

Clamper is a circuit that "clamps" a signal to a different dc level. The different types of clampers are positive negative and biased clampers.

A clamping network must have a capacitor, a diode and a resistive element. The magnitude R and C must be chosen such that the time constant RC is large enough to ensure that the voltage across the capacitor does not discharge significantly during the interval the diode is non- conducting.
