  • Position measuring system and method for operating a position measuring system
    Patent number: 6265992
    Abstract: A position measuring system for the determination of the relative positions of two objects which can be moved with respect to each other, as well as a process for operating the same are disclosed, which in case of a relative movement provides at least one pair of phase-shifted analog incremental signals, and which makes possible a definite variation of the signal periods (SP) by at least one signal period variation factor (n) of the analog incremental signals transmitted to an evaluation unit arranged behind it by a signal period variation unit.
