Abstract
A flux gate sensor having sense windings for providing an output proportional to the strength of an external magnetic field in which the sensor is placed. A gating circuit which is responsive to a pulse which is generated when the core of the sensor is driven into and out of saturation gates the output of the sense windings to a pair of filters which in turn provide an output proportional to the intensity of the external magnetic field. With two sense windings the outputs of the filters may be used to determine the direction of the magnetic field relative to the sensor and thereby be used as a compass.
