In what year did Edwin Armstrong create the first triode tube oscillator?
On Christmas Eve 1906 engineering professor Reginald Fessenden transmits a voice and music program in Massachusetts that is picked up as far away as Virginia. Columbia University electrical engineering student Edwin Howard Armstrong devises a regenerative circuit for the triode that amplifies radio signals.
What famous contribution did Edwin Howard Armstrong create to the advancement of radio?
frequency modulation
Armstrong’s attempt to eliminate radio static led to another industry-creating breakthrough, a radio circuit that operated on broadband frequency modulation (FM). The radio industry had all but given up on this holy grail, but by the end of 1933, Armstrong unveiled the product of five years’ toil.
Who invented am?
Reginald A. Fessenden. Reginald Fessenden is known for discovering amplitude modulation (AM) radio and explaining its scientific principles. With his heterodyne principle, he put into practice the idea of mixing two high frequency signals to carry the audible low frequency of the human voice.

Who invented the first oscillator?
De Forest ultimately won before the Supreme Court in 1934 on technical grounds, but most sources regard Armstrong’s claim as the stronger one. The first and most widely used relaxation oscillator circuit, the astable multivibrator, was invented in 1917 by French engineers Henri Abraham and Eugene Bloch.
