(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.
