Parallel resonant circuits are used to select frequencies because the voltage and impedance peak at resonance. Calculate the impedance of the resonant circuit specified in Problem 25.
Problem 25
In the FM radio band, which spans the frequencies from 88 MHz to 108 MHz, stations must be separated by 0.20 MHz. To avoid overlapping, stations must broadcast with a bandwidth less than that. If the bandwidth of an FM station, which has a cartier frequency of 100 MHz, is 70 kHz, calculate the Q-factor of the receiving circuitry
