Abstract
The resonant frequency of a device is determined by energizing the device with a short burst of energy to produce a decaying sinusoidal output, determining coefficients of a linear difference equation characterizing the decaying sinusoidal output by use of a least-mean-square fit, and determining the resonant frequency from the coefficients. The Q of the device can be determined from a decay parameter of the envelope of the decaying sinusoidal output and from the resonant frequency.
