  • Methods and apparatus for removing cyclic noise from the output signal of a magnetic sensor
    Patent number: 5343707
    Abstract: A cyclic noise removing method first generates a template of a cyclic noise caused by a cryogenic refrigerator, which template is generated by arithmetically averaging the output signal from a magnetic sensor by every vibration cycle of the cryogenic refrigerator, the magnetic sensor being cooled by the cryogenic refrigerator, then removes noise included in the output signal of the magnetic sensor by subtracting the template from the output signal of the magnetic sensor.
