In order to calculate the Q, quality factor for an inductor, the formula or equation below can be used: Q = X L R. As the resistance is equal to 2 π f L, this can be substituted in the formula to give: Q = 2 π f L R. Looking at these formulas it can be seen that the overall, inductive reactance, X varies according to the frequency. A higher value for this figure of merit corresponds to a more narrow bandwidth, which is desirable in many applications. It is the also referred to as the null Current (I): Enter the the current in Amperes (A). The center frequency is the frequency in the center point of the bandpass. Enter the power factor of the load. Q Factor is largely beholden to engineering constraints that are beyond the rider’s control, but stance width can be manipulated.

Explanation. The quality factor or the Q factor of an inductor at the operating frequency ω is defined as the ratio of reactance of the coil to its resistance.. So the quality factor again for a notch filter is the difference between the -3dB cutoff frequencies over the null frequency. And RLC or LC (where R=0) circuit consists of a resistor, inductor and capacitor, and can oscillate at a resonant frequency which is determined by the natural rate at at which the capacitor and inductor exchange energy. If the reaction rate increases with increasing temperature, Q 10 will be greater than 1. The 2D example file includes both the standard (high) Q analysis object, and the low Q analysis object. over the center frequency of the stopband, which is referred to as the null frequency or notch frequency. A high quality factor for a notch filter indicates the stopband is narrow. The Q factor equals 2 π times the exponential decay time of the stored energy times the optical frequency. Q 10 is a unitless quantity. This calculator is for educational purposes. For positive integers the calculator will only present the positive factors because that is the normally accepted answer. So, for a notch filter, the quality factor is the entire stopband from the -3dB cutoff points over the null frequency, where the attenuation is the greatest.
