Abstract
A method comprising: generating signals Sand Sby using a first sensor that is positioned at a first position relative to a rotating target, the signals Sand Sbeing generated in response to a magnetic field that is associated with the rotating target; generating signals Sand Sby using a second sensor that is positioned at a second position relative to the rotating target; and calculating a position of the rotating target based on a ratio of a first difference between the signals Sand Sand a second difference between the signals Sand S.
