E
T
= Total unadjusted error: maximum deviation between the actual and the ideal transfer
curves.
E
O
= Offset error: deviation between the first actual transition and the first ideal one.
E
G
= Gain error: deviation between the last ideal transition and the last actual one.
E
D
= Differential linearity error: maximum deviation between actual steps and the ideal
one.
E
L
= Integral linearity error: maximum deviation between any actual transition and the end
point correlation line.
