Abstract
A pulse signal generator comprises a magnetic element (1) capable of causing a large Barkhausen jump; a detector (2) provided relative to the magnetic element; a magnetic field generator (3) provided in vicinity of the magnetic element for applying a biasing magnetic field to the magnetic element for making a predetermined magnetization; and a magnetic circuit forming unit (4) provided in vicinity of the magnetic element for applying a main magnetic field to the magnetic element for causing a large Barkhausen jump in the magnetic element. The magnetic field generator is provided with magnetic field concentration means (32A) for concentrating the biasing magnetic field upon the magnetic element and the magnetic field adjusting means (74) for adjusting an intensity of the biasing magnetic field upon the magnetic element.
