Inventor: HORI TOSHIO
IPC: G05D1/00
Filed: 1991-02-14
Abstract: PURPOSE:To remove the zero offset from an angular velocity signal during the operation of a sensor by holding the zero offset detected when only the infrasonic wave components are selected in an erasing capacitor as a voltage signal. CONSTITUTION:When the zero offset of a sensor is varied with infrasonic waves, and the frequency of the angular velocity signal when an object oscillates is high, a zero offset detector 3 which outputs only the infrasonic frequencies from a sensor signal 1 detects a zero offset signal. This detecting signal is held in an erasing capacitor 4 as a voltage signal. The voltage signal is subtracted from the sensor signal 1 by a differential amplifier 5 thereby to erase the zero offset. Accordingly, the zero offset can be erased during the operation of the sensor.
