What is Sub-Divisional Error (SDE) in Linear Encoders?
To determine the position of a linear axis, an encoder read head travels along a scale and "reads" changes in light (for optical encoders) or magnetic field (for magnetic types). As the read head registers these changes, it produces sine and cosine signals that are shifted 90 degrees from each
