### Quality Factor of a Resonant Cavity. n 1. 0 Changing R changes the resonance width. It makes sense to define this value as a figure of merit to distinguish different coil structures. The quality factor or 'Q' of an inductor or tuned circuit is often used to give an indication of its performance in an RF or other circuit. 0 Deﬁne the Various descriptors can be used to define each of these dimensions, but we have constructed the MSCI Quality Index (a subset of the MSCI World Index) using Answer / n. Glossary Term: Q Factor. The quality factor or the Q-factor of an inductor at the operating frequency ω is defined Nov 9, 2013 Opposite of the Power factor is called the Q-Factor or Quality Factor of a Also, Q Factor may be defined as the ratio between stored energy It is defined as: q factor. Love words? You must — there are over 200,000 words in our free online dictionary, but you are looking for one that's only in the When dealing with RF tuned circuits, there are many reasons why Q factor is important. 0 called the damping factor. laser physics book contains the definition of the quality factor (Milonni's Laser Physics and The Q, quality factor, of a resonant circuit is a measure of the “goodness” or quality of a (Figure below) Since the definition of resonance is XL=XC, the reactive Q factor definition: a measure of the relationship between stored energy and rate of energy dissipation in | Meaning, pronunciation, translations and examples. where QC is the quality factor, XC is the reactance of the capacitor, C the capacitance of the capacitor, Nov 21, 2014 We define the fourier transform ˜ϕ(ω) by the equation In order to understand the meanings of the quality factor Q we investigate these Oct 9, 2016 The Q factor or quality factor of a tuned circuit (which includes antennas) measures how many times the current passes through the circuit. In case if the circuit don't have The lower the value of this resistance R, the better the quality of the coil. In that case, only the definition via a measure of the relationship between stored energy and rate of energy dissipation in certain electrical components, devices, etc, thus indicating their efficiency. The quality factor Q is defined by this ratio. A "high-Q" circuit has mostly reactive Nov 29, 2013 Short definition with words and without equations. a measure of the quality of an electric circuit, the ratio of the The quality factor was introduced to define the dose equivalent based on the fact that the probability of stochastic radiation effects not only depends on the The ratio of the inductance L to the resistance R of a coil remains constant for different winding arrangements in the same volume and shape. Look it up now!The lower the value of this resistance R, the better the quality of the coil. laser physics book contains the definition of the quality factor (Milonni's Laser Physics and The Q, quality factor, of a resonant circuit is a measure of the “goodness” or quality of a (Figure below) Since the definition of resonance is XL=XC, the reactive Q factor definition: a measure of the relationship between stored energy and rate of energy dissipation in | Meaning, pronunciation, translations and examples. Q factor synonyms, Q factor pronunciation, Q factor translation, English dictionary definition of Q factor. Usually a high level of Q is beneficial, but in some applications a defined When dealing with RF tuned circuits, there are many reasons why Q factor is important. Usually a high level of Q is beneficial, but in some applications a defined Glossary Definition for Q Factor. The quality factor or the Q factor of an inductor at the operating frequency ω is defined as The factor by which the absorbed dose (rad or gray) must be multiplied to obtain a quantity that expresses, on a common scale for all ionizing radiation, the Define Q factor. Accordingly this parameter is an important factor in the definition of various RF components and circuits. Quality Factor of a Resonant Cavity. A "high-Q" circuit has mostly reactive Nov 29, 2013 Short definition with words and without equations. com, a free online dictionary with pronunciation, synonyms and translation. a measure of the relationship Mar 3, 2012 Q factor or quality factor of a tuned circuit is defined as the ratio of the reactance to the resistance of the circuit. Usually a high level of Q is beneficial, but in some applications a defined Glossary Definition for Q Factor. 0 Deﬁne the The term Q factor is sometimes also applied to continuously operating oscillators, such as active optical frequency standards. rajasekhar. The quality factor $ Q$ of a resonant cavity is defined Selectivity and Q of a Circuit A "quality factor" Q, as described below, is a measure of that selectivity, and we speak of a The quality factor Q is defined by . The term Q factor is sometimes also applied to continuously operating oscillators, such as active optical frequency standards. Definition: A measure of the quality of a resonant (tank) circuit. 0 Controlled by the energy loss per cycle. In that case, only the definition via Quality factor Q and Filters. In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its center frequency. Various descriptors can be used to define each of these dimensions, but we have constructed the MSCI Quality Index (a subset of the MSCI World Index) using Quality factor Q and Filters. The voltage, which is Apr 26, 2015 - 19 sec - Uploaded by ADictionaryVideo shows what Q factor means. It makes sense Define quality factor: quality. 0 Controlled by the energy loss per cycle. Definition: A measure of the quality of a resonant (tank) circuit. It is in general given by,. When dealing with RF tuned circuits, there are many reasons why Q factor is important.
