Abstract
A method for determining two pseudo-sinusoidal signals in quadrature from a pseudo-sinusoidal signal transmitted by an encoder is provided. The method using a sensor arranged within reading distance of the encoder, which sensor includes at least four sensing elements which are linearly equally distributed. The sensing elements are each capable of delivering a signal Srepresentative of the signal transmitted by the encoder. The method measuring the signals Sand combining the signals Sin order to form the signals U=(S−S)−(S−S) and V=(S−S), which signals U and V are in quadrature. A system for determining by implementing such a method, as well as a bearing including such a determination system, are provided.
