Claim 19:
20. The demarcating system according to claim 16, wherein each of the plurality of sinusoidal current waveforms of the predetermined current waveform has a respective amplitude value Bk; and
wherein each of the sinusoidal voltage waveforms of the operating voltage waveform has an amplitude that is substantially proportional to, and substantially equal to, the product of: an impedance value, Zk, calculated for a sinusoidal voltage waveform having the same frequency, fk, and the amplitude value, Bk, for the sinusoidal current waveform having the same frequency, fk; and
wherein the instructions, when executed, further cause the one or more processors to determine each impedance value Z(fk) based on: the frequency, fk, of the sinusoidal voltage waveform in question; the resonant frequency, f0, and one or more values corresponding to the other sources of resistance and/or capacitance within the same circuit as the wire loop.
