Resistance law C (Reverse Audio/Anti Log) curve
Linearity
As a basis of assessing Linearity Tolerance the independent method is the most practical,
permitting as it does, the reference curve to be aligned as near as possible to the actual output
curve. This avoids the use of the theoretical starting and finishing points, it is normal for the
customer to realign the achieved curve with series trimmers at each end of the device if
required.
