Consider the circuit shown in figure. If the $$\beta $$ of the transistor is $$30$$ and $${{\rm I}_{CBO}}$$ is $$20$$ $$nA$$ and the input voltage is $$5V$$ then the transistor would be operating in

For given sinusoidal input voltage, the voltage waveform at point $$P$$ of the clamper circuit shown in figure will be

Assuming the diodes $${D_1}$$ and $${D_2}$$ of the circuit shown in the figure to be ideal ones, the transfer characteristics of the circuit will be

What are the states of the three ideal diodes of the circuit shown in figure?
