Max. angle
The angle can be counted from 0° to 360° or from 0° to 720°. When the end value has
been reached, the angle starts again at 0°. If the transducer outputs a quadrature signal,
the angle is counted forwards and backwards.
Angle interpolation
The angle values at the sampling instant are interpolated between the edges of the input
signals F1/F2.
Glitch filter
If double edges or interferences occur in the transducer, these can be rectified with the
aid of the glitch filter. 1μs means for instance that no further edges are evaluated for 1μs
after an edge has been detected.

Fig. 10.25 Speed and reference pulse T40B in direction of arrow
The positive edges of the reference pulse and the speed F1 occur at the same time. The
speed signal F2 leads by 90° compared to F1.
