What is a Q factor?
Q factor is the overall width of an installed crankset, measured parallel to the bottom bracket shell from the outside of one pedal insertion point to the other. You can think of it like this: the larger the Q factor, the farther apart your feet will be.
How is Q factor cycle calculated?
The Q Factor of a bicycle is the distance between the pedal attachment points on the crank arms, when measured parallel to the bottom bracket axle.
What is Q-factor in food cost?
This Q factor, also called a cover cost, is an estimate of the typical cost of food a guest will consume outside of listed menu items. In some restaurants, the Q factor may be only a few cents for items like salt, pepper and hot sauce.
What is 172mm Q-factor?
Q-Factor or crank width is the distance between the two pedal cranks and is a measure of stance width, which is similar to your walking step-width. QF Range. 135mm on an aerodynamic Road Bicycle to 235mm for a Fat Tire Bike.
Is higher Q factor better?
In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. Higher Q indicates a lower rate of energy loss and the oscillations die out more slowly.
How are poles and zeros used in digital filters?
Pole-Zero Analysis. This chapter discusses pole-zero analysis of digital filters. Every digital filter can be specified by its poles and zeros (together with a gain factor). Poles and zeros give useful insights into a filter’s response, and can be used as the basis for digital filter design.
Can a Q factor be reduced in a Butterworth filter?
Q-factor can also be reduced to make a maximally flat pass-band (aka a butterworth filter). The picture goes on to explain where the pole zero diagram comes from and how you can relate natural resonant frequency ( ω n) with zeta ( ζ ).
What does the Q factor on a high Q filter mean?
Looking at picture of frequency response, it seems that the high Q filter has a type of hump as it approaches the cut off frequency. Isn’t this a bad thing since ripple in pass band is not desired. In general terms, the Q factor will still refer to the steepness of the gain slope, no matter your selected filter type.
What’s the effect of Q on a low pass filter?
Here’s a picture (I drag out now and then) that explains the effect of Q on a 2nd order low pass filter: – The top three pictures show you the effect of varying the Q-factor. Q-factor can also be reduced to make a maximally flat pass-band (aka a butterworth filter).
