WebOct 4, 2024 · Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or … WebThe quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation meaning that it is a ratio of resonant frequency to bandwidth and the higher the circuit Q, the smaller the bandwidth, Q = ƒr /BW.
WebThe QF of the coil is Q = ωL1/R1 = 1/ ω2R4C4 The unknown capacitance & inductance equation mainly includes frequency term. Therefore to find the unknown inductance value, the supply frequency must be known. Here, the frequency doesn’t play an essential role in the high QF Q = 1/ ω2R4C4 Substituting this value in the L1 L1 = R2R3C4/1+ (1/Q)2 WebThe quality factor (Q) applies to any resonant circuit component; most often the quality factor of the coil determines the overall Q of the circuit. Inversely related to the fraction of the energy in an oscillating system lost in one oscillation cycle. Q is inversely related to the range of frequency over which the system will exhibit resonance.
