Question

For the circuit and the input signal shown which of the following is true for the output voltage?

(a) The output waveform is a square wave with lowest peak clamped to 0V

(b) The output wave is a square wave with lowest peak clamped to -6V

(c) The output waveform is a square wave with highest peak clamped to 4V

(d) The output waveform is a straight line with the value of output voltage equal to 10V

This question was addressed to me during an interview.

The question is from Limiting and Clamping Circuits and Some Special Types of diodes in division Diodes of Electronic Devices & Circuits

Answer 1

The correct choice is (a) The output waveform is a square wave with lowest peak clamped to 0V

For explanation I would say: It is a clamped capacitor circuit.
