(a)
Consider the simple RLC circuit shown in Fig. P1.1. Choosing the inductor
current and the capacitor voltage as the states or variables, obtain the two integral
equations for iL and vC in terms of the states or variables and the input voltage
(b) Obtain the SIMULINK simulation block diagram for the equations of (a).
