Question

For a sinusoidal input of 20 Vpeak to the given circuit, what is the minimum value of the output waveform?

(a) 20 V

(b) 25 V

(c) -25 V

(d) 0 V

The question was asked during an interview.

Query is from Diode Clipper and Clamper in division Diode Circuit of Analog Circuits

Answer 1

Right option is (d) 0 V

To explain I would say: The given circuit is a clipper that cuts off a part of the negative cycle of the input sinusoid i.e. the output becomes zero for a certain region of the input waveform. Hence, the minimum value is 0 V.
