Unformatted text preview: Quality Factor "Q" for Oscillations
Q x # of oscillation cycles in one 1/e amplitude decay time = (Measures persistence of free damped oscillations.) = T /2 A(f = fres) A(f = fres) Response Amplitude at resonance = = = Driving Amplitude Adrive A(f = 0) (Measures "amplification factor" at resonance or "height" of resonance peak for driven damped oscillations.) Resonance Frequency Full Width of resonance peak at 1/ 2 of its height fres f = = (Measures "sharpness" of resonance peak for driven damped oscillations) ...
