Notes: The function can only be carried out if the degree of stretching or contraction of the value range
derived from the minimum and maximum is not too large.

4.10.28 Fixed scaling
Parameter
Definition
Input channel
Channel to be re-scaled
Factor
New scaling factor, which together with the new offset determines a new value
range
Offset
New offset, which together with the new scaling factor determines a new value
range
Result channel
Re-scaled Input channel
Description: The value range of a channel is re-scaled on the basis of the new scaling factor and offset
supplied by the user. The new lower range limit L
L
and the new upper range limit L
U
are calculated by:
L
L
= -32767 * |Factor| + Offset and L
U
= +32767 * |Factor| + Offset
All sample values of the input channel are linearly transformed to fit the new result channel value range.
Notes: The function can only be carried out if the degree of stretching or contraction of the value range
derived from the specified scaling factor and offset is not too large.
