    Hi All,
    Measuring two different resonance circuits , one with air coil and the other with ferrite coil ,both with the same paralleled capacitor .
    The gain on the frequency response for the ferrite circuit is x10 than the air coil circuit , yet the ratio of Q=FC/BW is almost the same... (Q factor with ferrite is 85 with with air coil is 30 ).
    I think I am missing something , since the Gain factor dosn't been taken in account...

    Hope some one can give me a clue...

    Thanks ,
    Ron
