Digital electrical length or angle measuring device

Claim 1

Digital electrical measuring device, particularly an absolute measuring device with means for scanning at least one value representation with code groups of different resolutions and with means for adding unambiguously higher resolution code groups to coarser resolution code groups, wherein the improvement comprises means for connecting digitalized scanning signals (code values CW) of at least one coarser resolution code group (C 2 -C n ) to first addressing inputs (SE) of at least one fixed value storage (S) containing integral, non-rounded off, binary-stored calculated variants of such digitalized signals (CW) in tabular form; and means for alternately connecting such variants of the digitalized signals (CW) to outputs (SA) of said storage (S), in dependence upon the logical state of a control signal which is derived from the respective higher resolution code groups (C 1 ) and which is connected to a second addressing input (SE) of said storage (S), said variants including (CW+1)/2 for preceding signals and (CW+0)/2=CW/2 for non-preceding signals when the resolution of a higher resolution code group is double the resolution of a coarser resolution code group so that the calculated variants are dependent on a function of the resolution of the code groups, whereby a resolution of N-2 bits is achieved when a coarse resolution code is interconnected with an intermediate resolution code and a fine resolution code.
