Abstract: A method for demodulation including the following steps: exciting a vibrationally mounted, at least sectionally bar-shaped oscillating element for oscillating in the range of a resonance frequency of the oscillating element, wherein a temporally varying, in particular periodic, excitation signal is used for excitation, and wherein at least the temporal variation of the excitation signal is known or determined; detecting a modulated oscillation of the oscillating element by means of at least one sensor, wherein the sensor supplies a sensor measurement variable that varies versus time as a function of an amplitude and a phase of the modulated oscillation of the oscillating element. According to the present teaching, it is provided that the method includes the following step: generate a first comparison signal by amplitude modulating a known temporally varying, in particular periodic, demodulation signal by means of the temporally varying sensor measurement variable.
