A Tunable Tank Circuit The RLC circuit in Figure P12-81 (often called a tank circuit) has R = 4.7 kΩ, C = 680 pF, and an adjustable (tunable) L ranging from 64 to 640 μH.
(a) Show that the circuit is a bandpass filter.
(b) Find the frequency range in (Hz) over which the center frequency can be tuned.
(c) Find the bandwidth in (Hz) at the end points of this range.
