{{id}} {{{paragraph}}}
Frequency response: Resonance, Bandwidth, Q factor Resonance. Let s continue the exploration of the Frequency response of RLC circuits by investigating the series RLC circuit shown on Figure 1. RRCVR+-VsI Figure 1 The magnitude of the transfer function when the output is taken across the resistor is ()()222()1 VRRCHVsLCRC = + ( ) At the Frequency for which the term 21LC 0 = the magnitude becomes ()1H = ( ) The dependence of ()H on Frequency is shown on Figure 2 for which L=47mH and C=47 F and for various values of R.
Vs LC RC ω ω ωω ≡= −+ (1.1) At the frequency for which the term 1−ω2LC =0 the magnitude becomes H()ω =1 (1.2) The dependence of H(ω) on frequency is shown on Figure 2 for which L=47mH and C=47µF and for various values of R. 6.071/22.071 Spring …
