Angular Velocity Detecting Apparatus

摘要

An angular-velocity detecting apparatus including a synchronous-detection unit for performing the synchronous detection of a displacement signal from a vibrator, a unit for changing a voltage value so that the output of the synchronous-detection unit always becomes equal to its maximum value, the voltage value being applied to a resonant-frequency adjusting electrode, and a unit for feeding back the output of the voltage-value changing unit to the resonant-frequency adjusting electrode in a detection-axis direction.
