1. A method for electronic tuning of a frequency of a read oscillation to the frequency of a stimulation oscillation in a resetting Coriolis gyro, whereina resonator of the Coriolis gyro has a disturbance force applied to said resonator such thata) the stimulation oscillation remains essentially uninfluenced, andb) the read oscillation is changed such that a read signal which represents the read oscillation, contains a corresponding disturbance component, whereinthe disturbance force is defined as that force which is caused by a signal noise in the read signal, andthe frequency of the read oscillation is controlled such that a magnitude of the disturbance component, which is contained in the read signal, is as small as possible.
