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

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

For a system with the transfer function $$H\left( s \right) = {{3\left( {s - 2} \right)} \over {{s^3} + 4{s^2} - 2s + 1}},\,\,$$ the matrix $$A$$ in the state space form $$\mathop X\limits^ \bullet = AX + BU$$ is equal to
