WebA "quality factor" Q, as described below, is a measure of that selectivity, and we speak of a circuit having a "high Q" if it is more narrowly selective. An example of the application of resonant circuits is the selection of AM radio stations by the radio receiver. Webdefine 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 ...

WebJan 23, 2024 · Re: best way to measure Q. Q = wL/R = 2*pi*f*L/R has nothing to do with the SRF. You can measure Q at any frequency you like depending on the inductor and/or the circuit application. Q of a parallel resonant circuit is defined as q = f r /BW where f r is the resonance frequency and BW is the 3dB bandwidth. WebAs you can see, the amplitude of the signals halves in about 2.5 cycles and we can easily calculate the Q-factor by multiplying by 4.53 and we find Q = 11.3. The Q-factor of this tank is not very good: 11.4 is quite low, but it's not surprising. Small inductors like this one are mainly intended for switching power supplies and generally have a ...
