1. 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.

Examples of Q meter in a Sentence

1. Frederick Hubbard:

   Now, the question is, what do we need to do to get them to recover ? said Dr. Frank Ridgleyhead of conservation and research at Zoo Miami. Biologists believe they have the answer. Executives of the Patch of Heaven Sanctuary, a nonprofit organization dedicated to creating habitats for wildlife, in February finished building what they claim is the largest bat house in the world in an effort to save Floridas high flyers. Nobody else is doing this kind of work. Not on this scale, said Frederick Hubbard, the sanctuarys executive director. The two-tier structure can house up to 250,000 bats. The University of Florida boasts large bat houses of The University of Florida own.According to the [ UF ] web site, theyre the biggest occupied bat houses in the world, Frederick Hubbard told the Miami Herald. Our bat house is technically bigger. Were trying to get the wording right on that. Frederick Hubbard says the batstend to form colonies, living together and procreating. The new two-tier bat house can hold up to 250,000 total bats. ( Elina Shirazi/Fox News) Theres usually a dominant male, a large male who establishes and claims these coveted kinds of spaces and then he tries to attract females and the females tend to then be attracted to a male who is going to defend the territory and keep a safe space for them, Ridgley said. CLICK HERE TO GET THE FOX NEWS APP Ridgley says the bats are vital to biodiversity and in fact helpful to humans. Theyre cleaning up our skies. Theyre providing all these services and in some parts of the country, you know, bats literally provide billions of dollars of services to the residents, Ridgley said. Ridgley said its hard to know the history of the bats since they were only discovered as a unique species in 2004. There was very little known about this bat just about a decade ago. I mean they only knew of one place where they were roosting and it was a mystery across their whole range here in South Florida. Anything about them, you know, what kind of groups they had, what they need to survive. So there was a lot of intensive study going into answering some of these questions, said Ridgley. Ridgley estimates their population is now only in the hundreds, and technology is helping them to keep track. One device they use, an echo meter, plugs into a cell phone and identifies the type of bat and itslocation based off of sound. They do a type of echolocation and supposedly they have some recorded sounds that theyre going to be able to put up into the bat-house that will attract them, said Frederick Hubbard. Creators claim this bat house at the Patch of Heaven Sanctuary is the largest in the world. Frederick Hubbard said that if their project accomplishes its aim, it may help rewrite the fate of these bats who have lost almost all of their habitat. For now, Frederick Hubbard said they are patiently waiting for the bats to rent out their space. Come home.

2. Francesco Starace:

   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.

   If the sea level is rising by one meter, the map of Bangladesh will be changed.

4. Stewart Brand:

   Information Wants To Be Free. Information also wants to be expensive. Information wants to be free because it has become so cheap to distribute, copy, and recombine---too cheap to meter. It wants to be expensive because it can be immeasurably valuable to the recipient. That tension will not go away.

5. Marshall Perrin:

   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.
