Quality Factor

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	\(\large{sec}\)	\(\large{s}\)
