## Resonance Tuned Band Rejected Filter

Resonance Tuned Band Rejected Filter is an electronic device that has a unstable voltage over a band of selected frequencies when operate in resonance

### Characteristics

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

## Summary

Resonance Tuned Band Rejected Filter is an electronic device that has a unstable voltage over a band of selected frequencies when operate in resonance w1 - w2
