Title:
MAGNETIC DETECTOR
Document Type and Number:
Japanese Patent JP3396092
Kind Code:
B2
Abstract:
PURPOSE: To obtain a magnetic detector insusceptible to the environmental variation.
CONSTITUTION: In the magnetic detector 9, two rectangular AC voltages having same level of reverse phase are applied to a magnetic resistance element. Output voltage from the magnetic resistance element 2 is then amplified through an amplifier 3 including a high-pass filter. Two synchronism detectors 6, 7 detect two sync signals from the amplified voltage and the difference between two sync signals is determined.
