Рассмотрены научные пути, которые привели американского радиотехника Майкла Пупина к разработкам телефонных технологий, направленных на повышение качества звукового сигнала при его передаче на большие расстояния. Исследованы важные изобретения Пупина в области дальней телефонии. Описаны его теории использования катушек индуктивности для уменьшения затухания передаваемого телеграфного и телефонного сигнала по кабелю путем искусственного увеличения его индуктивности. Уделено внимание спору между Пупином и Кэмпбеллом в первенстве изобретения нагрузочных катушек и его наиболее значимым последствиям.

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.
