ABSTRACT:
A linear, path or angle dependent signal sequence (E) is formed from two path or angle dependent signals (A, B) of equal amplitude and period having an electrical phase offset to each other of 90.degree. and being generated by an incremental transmitter (GS), in that the transmitter signals (A,B) are rectified and an output signal is formed in a converter (U1), which [output signal] corresponds to the quotient of the respectively smaller absolute value (.vertline.A.vertline. or .vertline.B.vertline.) of the signals (A or B) to the sum (.vertline.A.vertline.+.vertline.B.vertline.) of the absolute values (.vertline.A.vertline., .vertline.B.vertline.) of both signals (A, B). The respective, precise position is detected from this signal sequence by means of a digital convervison.
