1.Objective:
• Understanding the operating principle of diode clipping circuit
• Understanding the waveform change of diode clipping circuits when the bias is applied.
2.Theory:
Theory of Operation:
As you know, diodes can be used as switches depending on the biasing type, reverse or
forward. The clipping circuit also referred to as clipper, clips off some of the portions of the
input signal and uses the clipped signal as the output signal.

3.1.2 Procedure:
1- Configure the function generator to output a sinusoidal signal with a frequency of
1K Hz and peak amplitude of 5V with a 0 V DC offset.
2- Connect the output of the function generator to the input of the oscilloscope and set
the controls on the oscilloscope: select channel 1.
3- Build the circuit shown in circuit figure 1 on your breadboard.
4- The voltage source will be your function generator, set the function generator with
the input signal that you obtained from 1.
5- Use the oscilloscope to view the voltage across VD on channel 2 and the input
voltage on channel 1.
6- Set the horizontal scale to show three periods. Then plot them in Graph 1.
