resonance method

resonance method

[′rez·ən·əns ‚meth·əd]
(electricity)
A method of determining the impedance of a circuit element, in which resonance frequency of a resonant circuit containing the element is measured.
(engineering)
In ultrasonic testing, a method of measuring the thickness of a metal by varying the frequency of the beam transmitted to excite a maximum amplitude of vibration.
