Abstract
An absolute position measurement system includes a multipole magnet comprising alternating magnetic poles extending along a multipole extension direction, the alternating magnetic poles generating a magnetic field. A magnetic sensor includes a first sensor element arrangement configured to generate a first signal in response to a first magnetic field component and a second sensor element arrangement configured to generate a second signal in response to a second magnetic field component. The absolute position measurement system is configured, as a position of the magnetic sensor relative to the multipole magnet changes, to generate a first oscillating sensor signal with decreasing first signal amplitude and to generate a second oscillating sensor signal with decreasing second signal amplitude based on the first and second signals. A processing circuit is configured to calculate an absolute position of the magnetic sensor based on the first oscillating sensor signal and the second oscillating sensor signal.
