Abstract
In a position measuring system, periodic scanning signals are obtained by scanning a measurement embodiment. These scanning signals are interpolated with greater precision with the aid of a subdivision circuit. Interpolation values are deposited in a memory unit in individual addressable storage units. The present invention reduces the required memory space to one eighth of its original size. In addition, the geometric arrangement of the memory unit is altered making the position measuring system adaptable to VLSI technology.
