m Incremental encoder: corrected header formatting
Tag: Reverted
Line 27:
An [[incremental encoder]] will immediately report changes in position, which is an essential capability in some applications. However, it does not report or keep track of absolute position. As a result, the mechanical system monitored by an incremental encoder may have to be [[homing (mechanical)|homed]] (moved to a fixed reference point) to initialize absolute position measurements.
