The quality factor, Q, defines the passive filter bandwidth. A passive filter with a high quality factor, Q, presents a larger bandwidth and better compensation characteristics. Eq. (41.67) defines the quality factor value in terms of the passive filter parameters L, R, and C. This equation shows that if R or C decreases, Q increases, and the

• The quality factor increases with decreasing R • The bandwidth decreases with decreasing R By combining Equations (1.9), (1.10), (1.11) and (1.18) we obtain the relationship between the bandwidth and the Q factor. 0 L B R Q ω == (1.19) Therefore: A band pass filter becomes more selective (small B) as Q increases.

Hard View solution 2021-01-28 · While there is no consistent definition of the quality factor (as there is with other factors), quality stocks typically have the following characteristics: low earnings volatility, high margins (profitability), high asset turnover (efficient use of capital), low financial leverage (little debt), low operating leverage (low fixed costs), and low specific stock risk.

Effects of Q Factor The quality factor refers to the tendency of high-quality stocks with typically more stable earnings, stronger balance sheets and higher margins to outperform low-quality stocks, over a long time horizon. The outperformance of high-quality stocks over low-quality stocks is well-documented in financial literature although the actual measure of “quality” is disputed. Metrics such as a Quality factor, Q Reactive components such as capacitors and inductors are often described with a figure of merit called Q. While it can be defined in many ways, it’s most fundamental description is: average power dissipated energy stored Q=ω Thus, it is a measure of the ratio of stored vs.
