| 摘要 |
The device has at least one pair of phase offset analogue incremental signals (SIN,COS) provided upon relative displacement of the relatively movable objects, transmitted to an evaluation circuit via a device (26) which provides a defined variation in the signal period of the incremental signals. The signal period variation device has a correction circuit (25,27,38) for eliminating errors in the incremental signals. The evaluation circuit may be supplied with incremental signals (SIN',COS') with at least 2 different signal periods.
