Abstract
The invention relates to a method for operating a mechanical resonator in an electronic oscillator, comprising determining a state space description of the resonator, in which state variables are the mass, the stiffness or dimensions of components used in the crystal resonator; providing a table with frequency correction factors as a function of a state space of a resonator; finding a frequency correction factor corresponding to the determined state space; and multiplying the output frequency of the resonator with the correction factor, and to an electronic oscillator, comprising a mechanical resonator, wherein an output frequency of the oscillator is multiplied by a frequency correction factor, the frequency correction factor being obtained from determination of the state variables of the resonator, in particular dominant mechanical state variables.
