Abstract: In a position measuring apparatus there is provided a subdivision circuit for the subdividing of sinusoidal scanning signals. The subdivision circuit includes rectifier circuits in which the scanning signals are reformed in such a way that over a total signal period one rectified signal always has a greater signal value than the other rectified signal. The rectified signal with the greater signal value lies on one reference input and the other rectified signal lies on the other reference input of an analog-to-digital converter. The analog-to-digital converter forms from these rectified signals a binary word which is fed to a correction arrangement. Together with code signals which define four equal sections of a single period, the correction arrangement generates a data word which represents intermediate values of a signal period of the scanning signals.
