Abstract

A method is described for balancing the phase-locked loop of an electronic analyzing device which analyzes the output signal of a sensor device, a yaw rate sensor in particular using the Coriolis effect having an oscillating mass which undergoes a deflection under the effect of an external yaw rate on the sensor device and the output signal representing a yaw rate signal, the electronic analyzing device having in addition to the phase-locked loop, a control loop, a quadrature control loop in particular, and the control loop is provided with a controller having an input and an output as well as with a modulator or mixer having an input which has a first electrical connection with the output of the controller. In order to reduce the percentage of sensor devices produced which, however, cannot be balanced the first electrical connection is interrupted between the output of the controller and the input of the mixer and a second electrical connection is produced between the output of the controller and the input of the mixer, the second electrical connection being made by connecting an attenuating element in between.
