实用电子学/调谐共振选择性带阻

R - LC

特征

${\frac {V_{o}}{V_{i}}}={\frac {j\omega L+{\frac {1}{j\omega C}}}{R+j\omega L+{\frac {1}{j\omega C}}}}$

$T=RC$

$\omega _{o}={\frac {1}{T}}={\frac {1}{RC}}$

R - LC//

特征

${\frac {V_{o}}{V_{i}}}={\frac {j\omega C+{\frac {1}{j\omega L}}}{R+j\omega C+{\frac {1}{j\omega L}}}}$

总结

以上两种配置可用于调谐共振选择性带阻滤波器
