摘要: Methods and Apparatus for detecting the presence of a conductor near an inductive coupling loop are disclosed. The method includes supplying an excitation to the coupling loop, measuring the signal distortion induced by the excitation signal, and monitoring the distortion in the signal for a change in harmonic content.
