CLIPPER

Clipper are circuits which can clip off or removes

unwanted portion of the input wave form without distorting

the rest of the wave form.

It is also known as Limiter, Slicers .

EXAMPLE

It is used for Amplitude limiting and Noise elimination.

SERI ES CLI P PERS AND PARALLEL O R SH UNT CLIPP ERS

The series clipper is defined as one where

diode is in series with the load, while the shunt

clipper has the diode in a branch parallel to the

load.

APPLICATIONS

There are numerous clipper application and it is not

possible to discuss all of them. However, In general clippers

are used to perfumed one of the following to functions.

Changing the shaped of the wave.

Circuit transient protection.
