  5. .. the Q (quality factor) of a resonant circuit, crystal, or resonator by measuring its series resistance at the resonance frequency. The Q is linked to the series resistance by two simple equations (R S is the series resistance, L and ...
    .. simple equations (R S is the series resistance, L and C the reactive elements and F R their resonance frequency): This Q-meter is unusual on more than one count: it is capable of displaying directly the value of the series resistance, and ...
