A parallel RLC network is constructed with a 200 μH inductor, and the remaining component values are chosen such that Q0 = 8 and ω0 = 5000 rad/s. Use approximate expressions to estimate the input impedance angle for operation at (a) 2000 rad/s; (b) 3000 rad/s; (c) 4000 rad/s; (d) 4500 rad/s. (e) Plot your estimates along with the exact result using a linear frequency (rad/s) axis.
