natural frequency

[′nach·rəl ′frē·kwən·sē]
(electronics)
The lowest resonant frequency of an antenna, circuit, or component.
(physics)
The frequency with which a system oscillates in the absence of external forces; or, for a system with more than one degree of freedom, the frequency of one of the normal modes of vibration.

natural frequency

One of a number of frequencies at which a system or object tends to vibrate if subject to a mechanical displacement or impact and then allowed to vibrate freely.
