Problem
The carrier frequency of a transmitter is provided by a tank circuit of a coil of inductance 49μH and a capacitance of 2.5nF. It is modulated by an audio signal of 12 kHz. The frequency range occupied by the side bands is:
(1) 18 kHz – 30 kHz
(2) 63 kHz – 75 kHz
(3) 442 kHz – 466 kHz
(4) 13482 kHz – 13494 kHz
