21. High voltage endurance requires multiple FET devices in series which adds series resistance and lowers the quality factor . 22. Piezoelectric resonators have not shown sufficient frequency stability or quality factor ( Q ) for frequency reference applications. 23. The ILFD locking range is inversely proportional to the quality factor ( Q ) of the oscillator tank. 24. Novation said the contracts were awarded on " clinical quality factors " and with input from hospital members. 25. Clocks, lasers, and other resonating systems that need either strong resonance or high frequency stability have high quality factors . 26. More precisely, the user agent provides an Accept HTTP header that lists acceptable media types and associated quality factors . 27. The size and shape of the cavity as well as the presence of interfaces also influence the quality factor . 28. The quality factor is useful in determining the spectral range of the resonance condition for any given ring resonator. 29. Coaxial transmission lines provide higher quality factor than planar transmission lines, and are thus used when higher performance is required. 30. The OEO is characterized by having very high quality factor ( Q ) and dispersion in the microwave frequency regime.
