ELECTRONIC CIRCUIT, VIBRATING GYROSCOPE, AND RELATED PROCESSING METHOD

摘要

The invention relates to an electronic circuit for a vibrating gyroscope that comprises a resonator, wherein the electronic circuit includes: an input for receiving a detection signal representing the vibration of the resonator, the detection signal including a specific vibration mode and a parasitic vibration mode; and a demodulation unit for demodulating the detection signal in order to generate a phase-demodulated detection signal and a quadrature-demodulated detection signal. The electronic circuit of the invention is characterized in that the same further comprises a processing unit (64) and a subtractor (70) for removing a portion of the detection signal that represents the parasitic vibration mode from the phase-demodulated detection signal and from the quadrature-demodulated detection signal.
