Square root function
A Square root function can be applied to the input.
Scaling of the function can be done as illustrated below:

Low cut-off function:
As a part of the square root function of the 4225 it is possible to manually configure a low cut-off point. The feature is often
used to suppress noise in the system.
The low cut off point defines a point where the input/output relationship either changes to a linear relationship or the output
is truncated to zero. The two principles are illustrated below:
