ABSTRACT:
From two path- or angle-dependent signals (A, B) of identical amplitude and period generated by an incremental generator (GS) which signals have a phase shift of 90.about. el. to each other a sequence signal .vertline.A.vertline./(.vertline.A.vertline.+.vertline.B.vertline.) dependent linearly on the path or angle is formed in that the generator signals (A, B) are rectified and a signal is formed in a converter (U1 ) corresponding to the quotient of the magnitude (.vertline.A.vertline.) of one of the two generator signals (A) to the sum of the magnitudes (.vertline.A.vertline.+.vertline.B.vertline.) of both generator signals (A, B). From the sequence signal the position within a particular quarter period is determined. Which quarter period this is in each instance is determined by an investigation of the position of the generator signals (A, B) with respect to each other.
