摘要：
In a method for generating pulse edges, assigned synchronously to the movement of a mechanical part, a magnetic field is generated. At least two measuring signals phase-shifted to one another for the magnetic field are detected. The magnetic field is changed as a function of the movement of the mechanical part in such a way that the measuring signals are modulated. A first measuring signal is compared with at least one first reference value. A second measuring signal is compared with at least one second reference value and/or the value of the first measuring signal is compared with the value of the second measuring signal. When at least one of these comparisons produces an agreement or the result of the relevant comparison changes its sign, a pulse edge is generated.
