A sensor such as a quartz angular rate sensor is operated in a closed-loop mode including feedback of a control signal. The sensor produces a modulated carrier frequency signal. For stable operation of the feedback loop, the control signal is obtained from the modulated carrier frequency signal by complex...http://www.google.fr/patents/US5400269?utm_source=gb-gplus-shareBrevet US5400269 - Closed-loop baseband controller for a rebalance loop of a quartz angular rate sensor
