Vibratory gyroscope

A vibratory gyroscope comprising:

• a vibrating body;
• an oscillation circuit for vibrating said vibrating body;
• two detecting piezoelectric elements formed on said vibrating body for detecting vibration of said vibrating body;
• a detection circuit for detecting an output signal difference of said two detecting piezoelectric elements, two input terminals of said detection circuit being connected respectively to said two detecting piezoelectric elements;
• a synchronized detection circuit for detecting an output of said detection circuit in synchronism with vibration of said vibrating body, an input terminal of said synchronized detection circuit being connected to an output terminal of said detection circuit;
• a smoothing circuit for smoothing an output of said synchronized detection circuit, an input terminal of said smoothing circuit being connected to an output terminal of the synchronized detection circuit;
• an integration circuit for integrating said output of said detection circuit, an input terminal of said integration circuit being connected to said output terminal of said detection circuit;
• and
• a composite circuit for composing an output of said smoothing circuit and an output of said integration circuit, one input terminal of said composite circuit being connected to an output terminal of the smoothing circuit, the other input terminal of said composite circuit being connected to an output terminal of the integration circuit.
