1. A detecting circuit for detecting an abnormal state i a vibrating gyroscope which generates an oscillation signal for driving a vibrator and a detection signal for detecting a rotary angular velocity of said vibrator, said detecting circuit comprising:

  • a first rectifying means for rectifying said oscillation signal;

    a second rectifying means for rectifying said detection signal in the direction reverse to said oscillation signal rectified by said first rectifying means;

    a composite means, operably coupled to said first and second rectifying means, for combining said oscillation signal rectified by said first rectifying means and said detection signal rectified by said second rectifying means, and for outputting a composite signal; and

    a switching device operably coupled to said composite means, wherein said switching device is switched by said composite signal from said composite means.
