Problem
In a table-top radio receiver the inductance of the tuning coil is 250μH, while the variable capacitor can be adjusted continuously between 50pF and 150pF.
(a) Determine the minimum and maximum resonant frequencies that can be obtained with this arrangement.
(b) The medium-wave (AM) broadcast band extends from 530kHz to 1.70MHz. By comparing with your results in part (a), state with justification whether the entire band can be covered by this tuning circuit.
