ABSTRACT:
A method for position determination in a position measuring device that includes digitizing analog position data from a detector unit within time intervals of an internal clock rate and calculating position data from the digitized data. Determining a period of time Δt between a pulse of the internal clock until an appearance of an external trigger signal and a processing of at least two position data, together with the period of time Δt.
