1. An angular velocity sensor for driving a vibrator in an X-axis direction and for detecting angular velocity based on vibrations caused by a Coriolis force generated in a Y-axis direction when said vibrator rotates about a Z-axis, said angular velocity sensor comprising:

  • a vibrator outputting a left signal and a right signal;

    a drive circuit connected to the vibrator;

    a converter connected to the vibrator for digitizing said left signal and said right signal; and

    an arithmetic operation unit for generating π

    /2 phase shifted signals and computing and outputting a magnitude of the Coriolis force based on the left and right signals and on the π

    /2 phase shifted signals.
