Q meter
A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of impedance measuring devices, though it is still in use among radio amateurs. It was developed at Boonton Radio Corporation in Boonton, New Jersey in 1934 by William D. Loughlin.

Q meter
A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of impedance measuring device, though it is still in use among radio amateurs. It was developed at Boonton Radio Corporation in Boonton, New Jersey in 1934 by William D. Loughlin. A Q meter measures Q, the quality factor of a circuit, which expresses how much energy is dissipated per cycle in a non-ideal reactive circuit: This expression applies to an RF and microwave filter, bandpass LC filter, or any resonator. It also can be applied to an inductor or capacitor at a chosen frequency. For inductors Where is the reactance of the inductor, is the inductance, is the angular frequency and is the resistance of the inductor. The resistance represents the loss in the inductor, mainly due to the resistance of the wire. For LC band pass circuits and filters: Where is the resonant frequency and is the filter bandwidth. In a band pass filter using an LC resonant circuit, when the loss of the inductor increases, its Q is reduced, and so the bandwidth of the filter is increased. In a coaxial cavity filter, there are no inductors and capacitors, but the cavity has an equivalent LC model with losses and the Q factor can be applied as well.

LaDawnna Burnett (1975 - ), Letters on Ethics:
Shame is that intrinstic meter of our own heart to tell us that we have failed to follow our own moral compass.
If nothingness could be measured, the level of his reflection would serve as a standard meter!
I am afraid that I might be jailed in Belarus, i am not afraid of being fired or kicked out of the national team. I'm concerned about my safety. And I think that at the moment it is not safe for me in Belarus. I didn't do anything, but they deprived me of the right to participate in the 200 meter race and wanted to send me home.
While we are visiting these homes, the same people that will shut the power off and take the old meter out ... can also put in fibre optic cables into the pipe going out to our cabin, what we are proposing is to give the opportunity to ... use our pipelines, do not destroy walls, do not break everything, just use that. This will reduce the cost of fibre cable laying by a factor of five.
We're going to be opening up a lot of new discoveries, hopefully, over the next few years in terms of exoplanet imaging and, in the long run, taking these technologies and scaling them to future 30-meter telescopes, and perhaps large telescopes in space, to continue direct imaging and push down towards the Earth-like planet regime.
