Abstract
A method for detecting a media device comprises generating a waveform on a bias node of a demonstration system. The waveform has a fundamental frequency that is greater than a maximum frequency of a media frequency range of the demonstration system. The waveform is rectified to produce a detection signal. An impedance between the bias node and a ground is modified in response to a coupling of the media device to the bias node. An output signal changes state in response to a change in the detection signal due to the modification of the impedance.
