More Information
Summary:The present invention relates generally to encoder systems used for tracking movement of mechanical structures and, more particularly, to a system and method for analyzing encoder output signals for information regarding phase and amplitude relationship of the signals. An encoder system may determine a plurality of intersection points for first and second encoder output signals produced by an encoder. Each intersection point may be determined by initiating a capture of sample points of each of the encoder signals and then examining the captured sample points.
