How did the Audion work?
The Audion was an electronic detecting or amplifying vacuum tube invented by American electrical engineer Lee de Forest in 1906. It was the first triode, consisting of an evacuated glass tube containing three electrodes: a heated filament, a grid, and a plate.
What was the Audion and what did it do?
As the first triode vacuum tube, the Audion revolutionized radio broadcasting–and made it more practical. Dr. Lee De Forest was an inventor, engineer, and the self-styled “Father of Radio.” In 1906, De Forest invented the Audion tube, allowing the detection and amplification of weak radio signals.
