Questions & Answers

Q: What is the purpose of bias potential in a clipper circuit?

The bias potential is applied to shift the output waveform and change the polarity or orientation of the diode in the circuit.

Q: How does the clipper circuit behave in the negative half cycle?

In the negative half cycle, the diode becomes reverse biased, making it an open circuit. The output voltage becomes equal to the applied bias potential.

Q: How is the positive half cycle divided in the clipper circuit?

The positive half cycle is divided into three parts based on the voltage relationship between the anode and cathode of the diode.

Q: What happens in the second part of the positive half cycle in the clipper circuit?

In the second part, where the input voltage is greater than the bias potential, the diode becomes forward biased, allowing the input signal to pass through without any clipping.
