A system and method are disclosed for improving resolution of an encoder or other position sensing device that provides one or more signals indicative of relative movement between two bodies. The signals are employed to determine an operating mode, which varies as a function of relative speed between the two bodies. In one operating mode, the system determines an indication of position by interpolating between position information of a table. Position also can be predicted in this operating mode, which can be used to update the position information. The table is populated with position information based on a sample of the signals from the position sensing device, such as to provide the position information for the table. In another operating mode, an indication of position is determined as a function of velocity and time.
