What is the half-power bandwidth of a resonant circuit that has a resonant frequency of 7.1 MHz and a Q of 150?

Explicación

Half-power bandwidth is the resonant frequency divided by Q, so a Q of 150 at 7.1 MHz gives roughly 47.3 kHz between the −3 dB points. The kilohertz-versus-hertz distractors come from dividing in the wrong direction or misplacing the decimal.
