(1) Example of an actual transfer curve

(2) The ideal transfer curve

(3) End point correlation line

ET=Total Unadjusted Error: maximum deviation

between the actual and the ideal transfer

curves.

EO=Offset Error: deviation between the first

actual transition and the first ideal one.

EG=Gain Error: deviation between the last

ideal transition and the last actual one.

ED=Differential Linearity Error: maximum

deviation between actual steps and the ideal

one.

EL=Integral Linearity Error: maximum deviation

between any actual transition and the end point

correlation line.
