The maximum impedance of a parallel RLC circuit occurs at the resonance frequency ω0 =1/√(LC). Using this angular resonance frequency expression and the quality factor at resonance Q=ω0CR = R√(C/L), find (a)the 3dB angular corner frequencies ω1,2 as functions of ω0 and Q(here, the susceptance is equal to the conductance), and (b) show that the practical formula Q= ω0/(ω2-ω1)used to measure the quality factor is consistent with the circuit definition given above. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.173.134.105
