(ar) John Renshaw Carson (* 28. Juni 1886 in Pittsburgh, Pennsylvania; † 31. Oktober 1940 in New Hope (Pennsylvania)) war ein US-amerikanischer Nachrichtentechniker. Er erfand die Einseitenbandmodulation (SSB). An der Princeton University erwarb er 1907 seinen Bachelor of Science, 1909 für Elektrotechnik und 1912 seinen Master. 1907/08 war er am MIT. Von 1912 bis 1914 war er in Princeton Dozent für Physik und Elektrotechnik. 1914 begann er bei der American Telephone & Telegraph (heute AT&T), wo er an Experimenten zum Sprechfunk teilnahm. 1915 erfand er die Einseitenbandmodulation, um mehrere Telefongespräche gleichzeitig über einen Stromkreis zu übertragen, und installierte die ersten Übertragungssysteme zwischen Pittsburgh und Baltimore. 1922 publizierte er eine mathematische Abhandlung zur Frequenzmodulation, in der er die Carson-Formel zur Bandbreite vorstellte. Edwin Howard Armstrong konnte später die Vorteile der Frequenzmodulation darstellen. Von 1917 bis 1925 analysierte er Filter-Effekte zur Amplitudenmodulation mittels Operatorkalkül, um Entwicklern die Möglichkeit zu geben, Übersprechen auf solchen Mehrwegeleitungen zu unterbinden. Von 1925 bis 1940 arbeitete er als Mathematiker und Elektrotechniker für die Bell Laboratories, wo er 1932 mit George C. Southworth Wellenleiter-Experimente durchführte. (de) John Renshaw Carson (June 28, 1886 – October 31, 1940) was an American transmission theorist for early communications systems. He invented single-sideband modulation and developed the Carson bandwidth rule for estimating frequency modulation (FM) bandwidth. In 2013 Carson was inducted into the Electronic Design Hall of Fame for his contributions to communications.
