Claim Text:
1. A position sensor arrangement comprising: a transformer based position sensor; a signal processing system connected to a plurality of outputs from said transformer based position sensor; a first cable peaking correction apparatus controllably coupled to said signal processing system, wherein said first cable peaking correction apparatus is a variable frequency excitation source coupled to an input of said transformer based position sensor; wherein said signal processing system is operable to control an excitation frequency of said variable frequency excitation source, and wherein said variable frequency excitation source is connected to said transformer based position sensor such that said variable frequency excitation source provides an excitation current for said transformer based position sensor; and wherein said signal processing system is configured to cause said variable frequency excitation source to operate at multiple different excitation frequencies when said position sensor arrangement is initialized and to select one of said excitation frequencies that results in a least amount of error in a reading from said transformer based position sensor using said signal processing system.
