Notch Frequency vs Inductance
Fórmula
## 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.
Ejemplo Resuelto
L=1 mH, C=10 nF to reject interference.
- 01f_notch = 1 / (2pi x sqrt(0.001 x 1e-8))
- 02f_notch = 50,329 Hz
Preguntas Frecuentes
Notch vs bandpass?
Notch rejects one frequency and passes everything else. Bandpass passes one band and rejects everything else.
Common uses?
Removing 50/60 Hz mains hum, eliminating specific interference frequencies.
How narrow is the notch?
Notch width depends on Q factor (component losses). Higher Q = narrower notch.
