Abstract:
Methods and systems for detecting an angular position of a rotating device are disclosed, including sensing and counting high-resolution transitions of a high-resolution digital sensor in response to the rotating device rotating; sensing low-resolution transitions of a low-resolution digital sensor in response to the rotating device rotating, the low-resolutions transitions being spaced apart at uneven angles; determining an angular position of the rotating device in response to determining a number of high-resolution transitions between pairs of low-resolution transitions.
