Digital pressure transducers employing force-sensitive resonators are designed according to a method that eliminates spurious mode resonances. The dimensional and geometrical relationships of the force-producing pressure elements and structures are chosen such that spurious modes of oscillation are not excited by the resonant modes of the force-sensitive resonators.
