TLE5011
General
The output signal of each bridge is only unambiguous over 180° between two maxima.
Therefore two bridges are orientated orthogonally to each other.
Using the ARCTAN function, the true 360° angle value can be calculated that is
represented by the relation of the X and Y signals.
Because only the relative values influence the result, the absolute size of the two signals
is of minor importance. Therefore, most influences to the amplitudes are compensated.
