(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.
