what is clipper circuit

A clipper circuit is an electronic circuit designed to prevent the output from exceeding a certain predetermined voltage level without distorting the remaining part of the applied waveform. It is used in various electronic devices like television receivers, computers, and radio transmitters.

Here are the steps to understand what a clipper circuit is:

1. Basic Definition: A clipper circuit 'clips' or removes the part of the input signal that is above or below certain levels, hence the name 'clipper'.

2. Function: The main function of the clipper circuit is to remove the part of the signal voltage that is beyond the requirement. It does not amplify or decrease the signal but only clips off the unwanted portion of the signal.

3. Types: There are two types of clipper circuits: Positive and Negative. Positive clipper circuits remove the positive parts of the input signal that are beyond the threshold level. Negative clipper circuits remove the negative parts of the input signal that are beyond the threshold level.

4. Components: The basic components of a clipper circuit are diodes, resistors, and a DC battery.

5. Applications: Clipper circuits are used in various electronic devices to limit the voltage. They are used in radars, digital computers, and television sets to protect the circuit from voltage spikes.

6. Working: When the input voltage is less than the threshold voltage, the diode is in the OFF state and the output voltage is equal to the input voltage. When the input voltage is more than the threshold voltage, the diode is in the ON state and the output voltage is limited to the threshold voltage.

In summary, a clipper circuit is a simple electronic circuit used to prevent a signal from exceeding a defined voltage level.
