Edwin Howard Armstrong (December 18, 1890 – February 1, 1954) was an American electrical engineer and inventor, who developed FM (frequency modulation) radio and the superheterodyne receiver system.
Edwin H. Armstrong was an American inventor who laid the foundation for much of modern radio and electronic circuitry, including the regenerative and superheterodyne circuits and the frequency modulation (FM) system.
Feb 27, 2023 · Edwin Howard Armstrong is widely regarded as one of the foremost contributors to the field of radio-electronics. Among his principal contributions were regenerative feedback circuits, the superheterodyne radio receiver , and a frequency-modulation radio broadcasting system .
Apr 1, 2002 · Much of the technology that has transformed modern life is based on the work of unusually creative people, many of whom remain relatively unknown. One striking example is Edwin Howard Armstrong ’13E ’29HON, who spent his adult life at Columbia, first as a student and then as a faculty member.
In 1980, Electronics Magazine published a 650-page special issue to commemorate 50 years of achievement in electronics; on its cover, the only portrait of an individual inventor is that of Edwin Howard Armstrong.
This seminar chronicles the life of Edwin Armstrong, the little-known but extraordinary inventor who patented the technology behind FM radio. Armstrong championed inventions that made modern radio possible, says Columbia's Yannis Tsividis in Columbia Magazine 's Living Legacies.
In 1918, he invented the superheterodyne circuit, a highly selective means of receiving, converting, and greatly amplifying very weak, high frequency electromagnetic waves. His crowning achievement (1933) was the invention of wide-band frequency modulation, now known as FM radio.
