    dear engineer, i'm just confused with how to calculate the q-factor of the resonant circuit of an FM transmitter circuit whereby i don't know how to estimate either the energy stored nor the dissipated.
    Thank you

    Q or (figure of merit), is found by the ratio of XL/RL or XC/RC. By resonating your tuned circuit at different frequencies, you will find a peak at a particular frequency, where the resonant voltage peaks and the Q is maximum. RL AND RC are the series resistances. General Radio Co. used to make a Q meter that was very handy for testing various LCR combinations.

    CHEERS!
