Which of the following statements(s) is/are incorrect with respect to tuning circuit?
Options:
(a) The antenna of a radio accepts signals from many broadcasting stations.
(b) To hear one particular radio station, radio is tuned to a particular frequency.
(c) The signals picked up in the antenna acts as a source in the tuning circuit of the radio, so the circuit can be driven at only one frequency.
(d) In tuning, we vary the capacitance of a capacitor in the tuning circuit such that the resonant frequency of the circuit becomes nearly equal to the frequency of the radio signal received.
