<p>This system (S) for processing electric signals delivered by a sensor unit, said electric signals comprising a sine electrical voltage (SIN) and a cosine electrical voltage (COS), comprises at least four comparators (C1, C2, C3, C4) adapted to compare a first parameter to a second parameter, said parameters being a mean output electrical voltage (Um) of the sensor unit and the voltage of the sine electrical signal (SIN) for a first comparator (C1), said mean output voltage (Um) and the voltage of the cosine electrical signal (COS) for a second comparator (C2), the voltages of the sine signal (SIN) and the cosine signal (COS) for a third comparator (C3), said mean output voltage (Um) and the average of the voltages of the sine (SIN) and cosine (COS) signals for a fourth comparator (C4). This system also comprises a first XOR gate (XOR1), having in inputs the output signals (U1, U2) of the first and second comparators (C1, C2), and a second XOR gate (XOR2), having in inputs the outputs signals (U3, U4) of the third and fourth comparators (C3, C4). The output signals (Ur1, Ur2) of the system (S) are the output signals of the first and second XOR gates (XOR1, XOR2).</p> |
