# Resonant Circuit

A circuit that contains both inductance and capacitance and is resonant at one frequency.

### Overcoupling

The degree of coupling beyond the critical point in resonant circuits which produces a dip at the resonant-frequency point on the response curve.

### Q

A symbol for the figure of merit of a resonant circuit.
