For information on the provided shaping functions and their formulas, see:
●
"About the linear functions"
●
"About the detroughing function"
●
"About the polynomial function"
The group of examples in this section uses the same linear shaping function to explain
the representation in the different voltage adaptation modes. The example explains the
displayed values and how they are calculated and converted. The same principle
applies for the other shaping methods.
