Notes:
(1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage
= (V_w(n)(actual) – V_w(n)(expected)) = ±1 Ml Maximum.
(2) 1 Ml = Minimum Increment = R_TOT/31.
(3) Relative Linearity is a measure of the error in step size between taps = V_W(n+1) – [V_w(n) + Ml] = +0.2 Ml.
