Processing circuitry is provided for processing a plurality of signals received from sense coils (21, 23 and 25) forming part of a position encoder used to encode the relative positions of two relatively movable members. The position encoder is such that each of the plurality of signals from the sense coils varies sinusoidally with the relative position of the members but out of phase with respect to each other. The processing apparatus comprises mixers (71, 73 and 75) for multiplying each of the received signals with one of a corresponding plurality of periodic time varying signals, each having the same predetermined period and a different predetermined phase, and an adder (93) for adding the signals from the mixers. The phase of the mixing signals are chosen so that the output signal from the adder contains a single periodic component having the predetermined period whose phase varies with the relative position of the two members.

Circuit de traitement servant à traiter une pluralité de signaux reçus depuis des bobines de détection (21, 23, 25) faisant partie d'un codeur de position utilisé afin de coder les positions relatives de deux éléments mobiles l'un par rapport à l'autre. Ce codeur de position est conçu de telle façon que chaque signal dans la pluralité de signaux provenant des bobines de détection varie selon une sinusoïde avec la position relative des éléments mais déphasé mutuellement. Le dispositif de traitement comprend des mélangeurs (71, 73, 75) servant à multiplier chacun des signaux reçus par un signal dans une pluralité correspondante de signaux à variation périodique dans le temps, chacun possédant la même période prédéterminée et une phase prédéterminée différente, ainsi qu'un additionneur (93) servant à additionner les signaux provenant des mélangeurs. La phase des signaux de mélange est sélectionnée de telle sorte que le signal de sortie de l'additionneur contienne une seule composante périodique possédant la période prédéterminée dont la phase varie avec la position relative des deux éléments.
