Question

7.27 The LC circuit shown in Fig. P7.27 (originally presented in Problem 3.25) is connected to an antenna and is the basic circuit component used in electrical oscillators and frequency tuners. The system parameters are L 3 m1H and C 20 μF. At time t-0-the capacitor is charged and its voltage is ec(0) 2.5 V, the switch is open, and there is no current in the circuit. At time t 0 the switch is closed. Accurately sketch the capacitor voltage ec(t) and current I(t) responses. Verify both sketches with a numerical simulation using Simulink and plot voltage ec() and current IC) responses from the simulation. Antenna Switch Figure P7.278.19 The LC circuit shown in Fig. P8.19 (originally presented in Problems 3.25 and 7.27) is connected to an antenna and is the basic circuit component used in electrical oscillators and frequency tuners. The system parameters are L- 3 mH and C 20 HF. At time the capacitor is charged and its voltage is ec(0) 2.5 V, the switch is open, and there is no current in the circuit. At time 0 the switch is closed Use Laplace transform methods to obtain the capacitor voltage ec(). Antenna Switch Figure P8.19The initial problem has been posted as requested. Than you in advance!
