An analogue output signal of a sensor which comprises a carrier signal with a carrier frequency &#x3c9;which is modulated by a measurement size is sampled with a sampling frequency &#x3c9;to receive a sampled sensor output signal. The frequency &#x3c9;of the sampling signal is set so that it is an integer divisor n of the carrier frequency &#x3c9;, wherein the phase of the sampling signal is set so that the sampling signal is synchronous to the sensor output signal. The sampled sensor output signal is filtered now to remove periodically repeated signal components from the sampled sensor output signal. Then a filtered useful signal is received, wherein its amplitude is proportional to the measurand detected by the sensor.

Method and device for processing analogue output signals from capacitive sensors

A rotational rate gyroscope for detecting rotation thereof comprises a base member, a primary oscillator supported by its primary oscillator suspension so as to be movable with respect to the base member, and a secondary oscillator supported by a secondary oscillator suspension, separate from primary oscillator suspension, so as to be movable with respect to the primary oscillator. The secondary oscillator suspension is designed such that movement that can be applied to the primary oscillator can be transferred to the secondary oscillator, whereas the movement of the secondary oscillator effected by the Coriolis force substantially is not transferred back to the primary oscillator. In addition thereto, the major surfaces of the primary oscillator and of the secondary oscillator extend substantially in the same plane, with the movement of the primary oscillator and/or of the secondary oscillator also taking place in this plane.
