Claim 2:
3. The system of claim 1, wherein the resistor is a first resistor, the cut-off frequency is a first cut-off frequency, and the series RC network is a first series RC network, and the envelope detector is a first envelope detector, the system further comprising a reference circuit comprising a second resistor, the first resistor and the second resistor having substantially the same resistance, and a capacitor, having a fixed capacitance, arranged to provide a second series RC network, having a second cut-off frequency that is not expected to vary with the presence of water within the electronic power steering system, that receives the excitation from the oscillator, the second series RC network providing an output in response to the excitation from the oscillator.
