Abstract
A digital electrical length or angle-measuring device connects digitalized scanning signals of at least one coarser revolution code group to first addressing inputs of one or more fixed value stores containing binary-stored calculated variants of the digitalized signals in form of tables, and the variants are alternately connected to outputs of the store in dependence upon the logical condition of the control signal which is derived from the respective higher resolution code groups and which is connected to a second addressing input of the store.
