  2. Q factor - Wikipedia

    en.wikipedia.org/wiki/Q_factor

    The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...

  3. Q Score - Wikipedia

    en.wikipedia.org/wiki/Q_Score

    The Q Score is a metric that determines a "quotient" ("Q") factor through mail and online panelists who make up representative samples of the population. The score identifies the familiarity of an athlete, brand, celebrity, poet, entertainment offering (e.g., television show), or licensed property, and measures the appeal of each among people ...

  4. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    The Q factor is a widespread measure used to characterise resonators. It is defined as the peak energy stored in the circuit divided by the average energy dissipated in it per radian at resonance. Low-Q circuits are therefore damped and lossy and high-Q circuits are underdamped and prone to amplitude extremes if driven at the resonant frequency.

  5. Q factor (bicycles) - Wikipedia

    en.wikipedia.org/wiki/Q_factor_(bicycles)

    The Q factor is an important factor affecting how close the pedals are laterally, and therefore the affects the spread of the riders legs. The Q factor or quack factor [1] [2] of a bicycle is the distance between the pedal attachment points on the crank arms, when measured parallel to the bottom bracket axle. [3]

  6. Transmissibility (vibration) - Wikipedia

    en.wikipedia.org/wiki/Transmissibility_(vibration)

    There is no unit designation for transmissibility, although it may sometimes be referred to as the Q factor. The transmissibility is used in calculation of passive hon efficiency. The lesser the transmissibility the better is the damping or the isolation system.

  7. Chu–Harrington limit - Wikipedia

    en.wikipedia.org/wiki/Chu–Harrington_limit

    The addition of this extra component creates a tuned circuit, with a Q-factor that potentially limits the instantaneous bandwidth available for signals passing through the antenna. This is a fundamental limit that sets a minimum size for any antenna used at a given frequency and with a given required bandwidth.

  8. Band-pass filter - Wikipedia

    en.wikipedia.org/wiki/Band-pass_filter

    A band-pass filter can be characterized by its Q factor. The Q-factor is the reciprocal of the fractional bandwidth. A high-Q filter will have a narrow passband and a low-Q filter will have a wide passband. These are respectively referred to as narrow-band and wide-band filters.

  9. Q meter - Wikipedia

    en.wikipedia.org/wiki/Q_meter

    A Q meter measures the quality factor of a circuit, Q, 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.
