Compensations (K3)
5.7 Neural quadrant error compensation
Case 2:
Coarse quantization > 1; fine quantization > 1; "Detailed learning" is deactivated (this setting
is the default):
In this case, discrete linear interpolation is used for fine quantization between the
interpolation points of the coarse quantization.
The learning duration is identical with 1 because learning only occurs at the interpolation
points of the coarse quantization.
The effect of fine quantization on a section of characteristic within a coarse quantization
process is shown in the diagram below (see also Section A in diagram above).
