Due to the increase in current, the voltage across L and C are also increased. equation (4) as where Qi and ∆ti are the quality factor and the traveltime in layer i, respectively. Taking an approach from velocity estimation, we assume straight ray paths and assume that quality factors and traveltimes in layers above layer N are known. Now we can calculate quality factor QN as where 2 2 2 2 p m m p f f − f α= and define a parameter called the Quality Factor Q which is related to the sharpness of the peak and it is given by maximum energy stored 22 total energy lost per cycle at resonance S D E Q E ==ππ (1.13) which represents the ratio of the energy stored to the energy dissipated in a circuit. The energy stored in the circuit is 2 11 S 22 E =+LI CVc2 (1.14) Quality factor is the ratio of reactance and resistance.
Given, The Quality factor for an ideal series RLC circuit and for a tuned radio frequency receiver (TRF) is given below. where the resistance, inductance and capacitance of the tuned circuit are R, L and C. When the resistance of the sequence is greater, the lower will be the value of Q in the circuit. equation (4) as where Qi and ∆ti are the quality factor and the traveltime in layer i, respectively. Taking an approach from velocity estimation, we assume straight ray paths and assume that quality factors and traveltimes in layers above layer N are known. Now we can calculate quality factor QN as where 2 2 2 2 p m m p f f − f α= and Pay attention to the (*) field,this is the field which can not explicitly expressed from other variable and should be calculated Iteratively, i.e in the first iteration you should enter dummy value in this field along with the other fields value and run the calculation, in the next iteration adjust the value of other fields to get the desired result for example in the sum of n term of GP Quality factor or Q–factor. The current in the series RLC circuit becomes maximum at resonance.
Formula: Q = R 1 C L Conditions for the large value of Q factor: (i) Value of C L should be large. (ii) Value of R should be less.
This tutorial explains how to calculate the Q factor of mechanical systems. Formula: Mechanical Quality factor =√MK / D. Where,. M=Mass K=Spring constant D=
Does the energy dissipated per cycle assume that the amplitude is constant from one cycle to the next. Quadratic equations can be factorised rapidly with this cool fast math trick.
The quality factor (Q-factor) calculator calculates the quality factor of either a bandpass filter circuit or a notch filter circuit. For a band pass filter, the quality factor is the ratio of the center frequency of the bandpass over the entire bandpass region from the lower to upper cutoff frequencies.

Quality Factor The energy loss rate of a weakly damped (i.e., ) harmonic oscillator is conveniently characterized in terms of a parameter, , which is known as the quality factor . This quantity is defined to be times the energy stored in the oscillator, divided by the energy lost in a single oscillation period.

The Q or quality factor is used by experts of resonators to rate how good a resonator is. It is similar to the time constant but instead of seconds, it is a measure of the decay time (i.e. ring time) of a shock-excited resonator in terms of radians (i.e. 2π times the decay time in cycles).
