EMC Was There at the Beginning


The Chicago Chapter and co-sponsoring EMCS units welcomes everyone to this informative and entertaining presentation about the roots of our profession.

The practice of electromagnetic compatibility (EMC) is generally understood as beginning with the military in the 1950s. Work in the field was mostly limited to military applications until about 1980, when the FCC in the US and agencies
 in other countries responded to broadcast interference complaints by setting RF emission limits on commercial products.  Though it wasn’t called EMC at the time, those techniques were applied in the late 19th century.
  Guglielmo Marconi’s company  demonstrated wireless telegraphy to the British navy, hoping for a contract to sell the equipment.   However, the spark-gap noise bursts transmitted by Marconi’s wireless limited communication to one pair of devices at a time and  Marconi had to fix it in order to close the deal. 

The stories of ambition, salesmanship, and resourcefulness give a colorful backdrop to our work in EMC.  In many ways, EMC practices can be traced back to the very beginning of the radio art. This talk will relate those stories and give a deeper perspective on the often unappreciated work of the EMC engineer.
