Quality Factor So what’s the magic about this circuit? The rst observation is that at resonance, the voltage across the reactances can be larger, in fact much larger, than the voltage across the resistors R. In other words, this circuit has voltage gain. Of course it does not have power gain, for it is a passive circuit.

At resonance, the reactance of the inductor and that of the capacitor have the same value: w 0 L=1/(w 0 c) The formula Q=w 0 L/R=1/(w 0 CR) hold for a series RLC circuit. An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC. The Quality Factor, or Q Factor, describes how under-damped a resonator is; the higher the Q factor the less damping there is. In an electrical resonator circuit damping is caused by the loss of energy in resistive components. In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is.

In the second part, you will drive the RLC circuit with a sinusoidal voltage and find the resonance frequency, ωres, and amplitude, Ares, of the system. The bandwidth and quality factor of the system, ∆ω and Q, respectively, will also be found, along with the circuit’s response curve.

from the numerator of the Q factor. The meaning and difference of the two definitions is investigated using an RLC series circuit, and the findings are presented

RLC circuits. In an ideal series RLC circuit, and in a tuned radio frequency receiver (TRF) the Q factor is: Q = 1 R L C = ω 0 L R = 1 ω 0 R C {\displaystyle Q= {\frac {1} {R}} {\sqrt {\frac {L} {C}}}= {\frac {\omega _ {0}L} {R}}= {\frac {1} {\omega _ {0}RC}}} Q = 1 2 ζ = A p k 2 + 1 for peak gain Apk When Q is the quality factor of resonance gain approaches 1 or less, we switch to damping factor as resonance becomes dampening factor is more relevant. Rule of Thumb: We approximate high Q to be just the resonant gain for Q>>1.
