Definitions for "Quality factor"
Keywords:  rad, dose, multiplied, damped, gamma
Dependent factor by which absorbed doses are to be multiplied to account for the varying effectiveness of different radiations.
An LET-dependent factor by which the absorbed doses are multiplied to obtain (for radiation protection purposes) a quantity which corresponds more closely to the degree of the biological effect produced by x or low-energy gamma rays. Dose in Gy × Q = Dose equivalent in Sv.
(Q) is the number of oscillations required for a system's energy to fall off by a factor of 535 due to damping.
In a reactive circuit, the ratio of the reactance in ohms divided by the resistance in ohms.
The ratio of capacitive reactance to resistance. The symbol used is (Q).
The ratio of the stored versus transmitted energy. For a capacitor "Q" defines performance. For an enclosure where microwave circuits are operating, Q impedes the performance of a device.
Also known as 'Q'. Another word for bandwidth. Q is defined as the center frequency divided by the bandwidth.
Is a measure of damping. Modern home speaker systems have Q values ranging from .5 to approx. 2.0. Q values .7 have no peak in the response. Q values around .5 are considered to be optimally damped, having a Bessel response. A Q of 1.0 is a Butterworth response. The lower the Q value, the better the transient response of the system, (less or no ringing), but the tradeoff is a larger required box size and the response begins to rolloff at a higher frequency. Another way to consider it is that the lower the Q, the more gradual the rolloff but the rolloff begins at a higher frequency.
(a.k.a., quality attribute or “ility”) an important attribute or characteristic of a work product (e.g., application, component, or document) or process that characterizes part of its overall quality (e.g., extensibility, operational availability, performance, reusability, or usability). Contrast with quality metric and quality requirement.
