MAGNETORESISTIVE TRANSDUCER Russian patent published in 2003 - IPC

FIELD: magnetometry; separation of low-frequency component of amplitude-modulated magnetic field. SUBSTANCE: proposed transducer having V- shaped static current-voltage characteristic functions to directly convert amplitude- modulated magnetic field to low-frequency voltage equivalent to modulating signal. Connected in parallel with sensing element of transducer incorporating one or more magnetoresistive strips is capacitor of respective rating. Voltage whose oscillation frequency equals modulating-signal frequency is set up across transducer output. EFFECT: enlarged functional capabilities. 1 cl, 4 dwg
