Abstract
An angular velocity detection apparatus is disclosed. The angular velocity detection apparatus includes: a SAW angular velocity sensor; a synchronous detection unit configured to synchronously detect an output signal from the SAW angular velocity sensor by using a reference signal; and a switching signal generation unit. The switching signal generation unit cyclically switches on and off an input of a driving signal to the SAW angular velocity sensor, and switches on an input of the output signal to the synchronous detection unit when an unwanted wave is un-inputted to a sensing electrode of the SAW angular velocity sensor.
