A phasor diagram of the voltages and current, The quality factor Q of a series resonant circuit is defined as the bandwidth (BW) of the resonant circuit. Electrical Tutorial about Parallel Resonance and Parallel RLC Resonant The bandwidth of a parallel resonance circuit is defined in exactly the same way as 14 Mar 2017 In order to get bandwidth of RLC circuit we have to find impedance first For the circuit Impedance is given by Z=Vs/I Z=R+j{wL-(1/jwC)} Resonance results The 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 = ?r /BW. Let's continue the exploration of the frequency response of RLC circuits by investigating . define a parameter called the Quality Factor Q which is related to the23 Jul 2017 9 Oct 2016 Bandwidth And Power Of Resonant Circuit. Bandwidth of Resonant circuit. Bandwidth is “the range of frequency from lower –3dB point to the higher –3dB point of frequency”. –3dB point of frequency is defined as the frequency of a signal that allows or pass with a magnitude of 0.707 of signal at resonant frequency. The 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 = ?r /BW. The Q, or quality, factor of a resonant circuit is a measure of the “goodness” or quality (Figure below) Since the definition of resonance is XL=XC, the reactive
