Abstract
A method and apparatus for enabling the operative association of electronic devices that each employ spread spectrum EMI noise reduction. The method includes the detection of frequency modulation and the generation of a modulation detection signal that conveys the modulation extent and type. The modulation detection signal is then used to accommodate the modulation technique and make it compatible with the receiving electronic device. The apparatus of the invention includes an FM modulator that creates an FM signal from an input signal, an FM detector that detects the FM content of the incoming signal and represent this information by means of either voltage or current signals, and a circuit to process this FM information and perform functions such as modification of the FM content and generating a new signal with this new content, complete removal of the content, and 'no-action,' whereby the signal is passed on with no alteration to the content.
