ABSTRACT:
A pulse signal generator comprises a magnetic element capable of causing a large Barkhausen jump, a detector provided in relation to the magnetic element, a magnetic field source provided in the vicinity of the magnetic element to produce a biasing magnetic field which causes a predetermined magnetization of the magnetic element, and a magnetic circuit forming member provided in the vicinity of the magnetic element to produce a main magnetic field which cause a large Barkhausen jump in the magnetic element such that movement of the object to be detected changes the main magnetic field of the magnetic circuit forming member thereby causing a large Barkhausen jump to provide a pulse signal.
