Consider the circuit in Figure 6.46.
1. Find the transfer function relating X(s) to the current in the inductor flowing to the right.
2. Derive the differential equation representing the transfer function.
3. Obtain the state-space model.
4. Obtain the impulse response representation.
5. Use any representation to find y(t) due to a step input of unity magnitude.
6. Draw the block diagram.
