實用電子學/調諧共振選擇性帶阻

R - LC

特徵

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

$T=RC$

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

R - LC//

特徵

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

總結

以上兩種配置可用於調諧共振選擇性帶阻濾波器
