In electronics, a clipper is a device designed to prevent the output of a circuit from exceeding a predetermined voltage level without distorting the remaining part of the applied waveform. A clipping circuit consists of linear elements like resistors and non-linear elements like junction diodes or transistors, but it does not contain energy-storage elements like capacitors. Clipping circuits are used to select for purposes of transmission, that part of a signal wave form which lies above or below a certain reference voltage level. Thus a clipper circuit can remove certain portions of an arbitrary waveform near the positive or negative peaks. Clipping may be achieved either at one level or two levels. Usually under the section of clipping, there is a change brought about in the wave shape of the signal. 

1.     Connect the circuit as shown in the circuit diagram.

2.     Give the input signal as specified.

3.     Switch on the power supply.

4.     Note down the value of AC and DC voltages from the CRO

5.     Draw the necessary waveforms on the graph sheet.

1.     Observe the output waveform from CRO.

2.     Measure the value of AC and DC voltages of the output and the input waveforms from the CRO.

3.     Observe and compare the maximum and minimum vltages of the input and output waveforms. 

From the Output waveform the following parameters has been observed and tabulated down below:

The Clipper circuit design output waveforms have been studied and the required parameters has been compared. 

 

1.     Connections should be verified before clicking run button.

2.     The resistance to be choosen should be in Kohm range.

3.     Best performance is being obtained within 50Hz to 1Mhz.
