Abstract

The scientific ways that led the American radio engineer Michael Pupin to the development of telephone technologies aimed at improving the quality of an audio signal when it is transmitted over long distances are considered. Pupin’s important inventions in the field of long-distance telephony are investigated. His theories of using inductors to reduce the attenuation of the transmitted telegraph and telephone signal over the cable by artificially increasing its inductance are described. Attention is paid to the dispute between Pupin and Campbell in the primacy of the invention of load coils and its most significant consequences.
