A method of detecting an angular velocity including generating a differential signal from a pair of detecting signals, each of the detecting signal including a component corresponding to a vibration of a vibrator (1) and a component corresponding to a Coriolis force proportional to angular velocity if the vibrator (1) is rotated; generating a timing signal based on the sum of the detecting signals; and applying the differential signal to a voltage-time converter (8) which, based on the timing signal, converts the differential signal to a pulse train having a duty cycle proportional to the angular velocity. The method is implemented in an angular velocity detector, such as a gyroscope (101). <IMAGE> |
