A rotary position sensor device comprises a rotary position sensor and an electronic circuit. The rotary position sensor includes a rotatable magnet creating a magnetic field and at least one pair of first and second peripheral magnetic field sensors. The magnetic field sensors of each pair are offset by 90° to each other and produce two signals which correspond to Sine- and Cosine-values of the rotational position of the magnet. The electronic circuit is configured to modulate the two signals of each pair with a time-dependent sinusoidal function and to produce at least one pair of modulated output signals. |
