## Notch (Band-Reject) Filter
**f_notch = 1 / (2pi x sqrt(LC))**
A notch filter rejects a narrow band of frequencies while passing all others. The rejection frequency uses the same LC resonance formula.
**f_notch = 1 / (2pi x sqrt(LC))**
A notch filter rejects a narrow band of frequencies while passing all others. The rejection frequency uses the same LC resonance formula.
计算示例
L=1 mH, C=10 nF to reject interference.
- f_notch = 1 / (2pi x sqrt(0.001 x 1e-8))
- f_notch = 50,329 Hz
