Claim 16:
17. A control unit for demodulation, wherein the control unit is connectable to at least one excitation means for exciting a vibrationally mounted, at least sectionally bar-shaped oscillating element, wherein the control unit can be connected to at least one sensor for detecting a modulated oscillation of the oscillating element, wherein the control unit is formed to execute a method according to claim 1, wherein the at least one sensor comprises a piezoresistive element and the sensor measurement variable is the electrical resistance of the piezoresistive element, wherein a voltage divider is provided to generate the first comparison signal, wherein the voltage divider is formed from a first electrical resistance and a second electrical resistance, and wherein the second electrical resistance includes the electrical resistance of the piezoresistive element.
