Abstract
A number of solutions for deriving the line bias are disclosed. Some of these solutions utilize signal processing and judicious selection of the frequency plan used in the position detection systems to either enable the derivation of the line bias, or make the measurements insensitive to line bias. In other examples, the present invention utilizes measurement schemes for deriving the line bias and enabling a position detection system to process line bias information in order to find a position solution.
