Arrangement for the production of straight-line symmetrical signals

摘要

An arrangement for the production of straight-line symmetrical signals from at least two signal generators, which have a periodic structure and which are movable relative to one another, by means of sensors that generate signals corresponding to the position of the signal generators, wherein at least two sensors are provided for at least one of the two signal generators with the output signals of the two sensors being combined in a subtraction or addition stage. The two sensors are positioned to be offset with respect to each other by one half period of the structure of signal generator or by an integer multiple of such period.
