From Radio Interference to Electromagnetic Compatibility — Classification of the Electromagnetic Environment

Abstract

In 1933 several international organisations met in Paris, to see, whether measures could be taken, to improve the quality of the reception of audio broadcasting. During the last ten years before that date, radio broadcasting had grown from reception by a few amateurs to very widespread reception. The quality of the transmitted programmes had improved and famous orchestras like the Amsterdam Concertgebouw Orchestra contributed. Under these circumstances radio interference became a real problem.
