Abstract
DISPOSITIVO DETECTOR DE CAMPO MAGNETICO.CONSTA DE UN MODULADOR PARA VARIAR EL AJUSTE DEL ELEMENTO SENSIBLE AL CAMPO MAGNETICO; Y DE UN CIRCUITO DE DETECCION PARA DETECTAR LAS VARIACIONES DE LA SEN/AL EN LA SALIDA DEL ELEMENTO EN FUNCION DE LA VARIACION DEL AJUSTE, AL OBJETO DE PRODUCIR UNA SEN/AL DE SALIDA EN LA QUE SE REDUZCA LA INFLUENCIA DEL COMPONENTE DE ERROR QUE SE FORMA, DEBIDO AL HECHO DE QUE HAY PRESENTE UNA SEN/AL EN LA SALIDA EN AUSENCIA DE UN CAMPO MAGNETICO.
