Abstract
A method determines a resonance frequency of a resonant device. The method includes stimulating the resonant device with a periodic input signal having a frequency in a frequency interval; determining a frequency value for said periodic input signal in said frequency interval for which a phase-difference between said periodic input signal and a corresponding periodic output signal of the resonant device is minimum; generating a flag indicating that a resonance frequency has been determined; and generating signals representing said resonance frequency as a value of the frequency of said periodic input signal.
