Draft
General
The output signal of each bridge is only unambiguous over 180° between two maxima.
Therefore two bridges are orientated orthogonal to each other.
Using the ARCTAN function, the true 360° angle value can be calculated which is
represented by the relation of the X and Y signals.
As 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.
