Question
An asymmetrical periodic pulse train of amplitude with on-time and off-time is applied to the circuit shown in the figure. The diode is ideal.
The difference between the maximum voltage and minimum voltage of the output waveform (in integer) is ________ V.

Correct answer
10 to 10
Solution
The circuit is a clamping circuit. For an ideal diode, the output waveform is a shifted version of the input waveform. The peak-to-peak voltage of the output waveform is identical to the peak-to-peak voltage of the input waveform.Input is a pulse train of amplitude. Thus, .Therefore, the difference between the maximum and minimum voltage of the output waveform is .
