This function models a non-linear transfer characteristic by linear approximation.
The output corresponding to an input between two transfer characteristic points XC(J), YC(J) and XC(J+1), YC(J+1) is determined by linear interpolation between the points. That is,
The output corresponding to an input that is either less than XC(1) or greater than XC(N), is determined by linear extrapolation, based on the nearest two data points. The XC data points must be increasing from XC(1) to XC(N).
