Quality Factor

on . Posted in Dimensionless Numbers

Quality factor, abbreviate, also called Q Factor or Q-factor, a dimensionless number, is the underdamped condition of an oscillator or resonator.


Quality Factor formula

\(\large{ Q  = \frac{ \tau \; \omega_0  }{ 2 }    }\)  
Symbol English Metric
\(\large{ Q }\) = quality factor   \(\large{dimensionless}\)
\(\large{ \omega_0 }\) (Greek symbol omega) = angular resonant frequency \(\large{\frac{1}{sec}}\) \(\large{\frac{1}{s}}\)
\(\large{ \tau }\) (Greek symbol tau) = expoential time constant \(\large{sec}\) \(\large{s}\)
