Abstract
A magnetic detection device is provided in which a first signal is outputted in accordance with the mutual phase relationship between the output of a first magnetoelectric conversion output circuit and the output of a second magnetoelectric conversion output circuit that are based on the movement, in forward direction, of a detection subject, thereby generating a pulse of a high leveland a low level; a second signal is outputted in accordance with the mutual phase relationship between the output of the first magnetoelectric conversion output circuit and the output of the second magnetoelectric conversion output circuit that are based on the movement, in forward direction, of the detection subject; an output signal processing circuit for generating a pulse of a high leveland a low levelis provided; and not only the pulse of the high leveland the low leveldoes not cross the other comparison level, but also the pulse of the high leveland the low leveldoes not cross the one comparison level.
