AUDION Meaning and
Definition
-
Audion is a noun referring to a type of vacuum tube that was invented by American electrical engineer Lee De Forest in the early 1900s. It is considered as an early predecessor of the transistor and played a significant role in the development of electronic amplification and communication systems. The audion tube consists of a glass envelope containing at least two metal elements, known as electrodes or plates, which are separated by a vacuum. These elements typically include a cathode, an anode, and a grid.
The audion tube operates based on the principles of thermionic emission and the control of current flow through an external voltage applied to the grid. When a small voltage is applied to the grid, it controls the flow of electrons from the cathode to the anode, thus allowing amplification of electric signals. This phenomenon provides a means to amplify weak signals, making them stronger and more conducive for transmission or other applications.
Audion tubes have been utilized in various applications, including early radio receivers, telephone systems, wireless telegraphy, and other communication devices. While they have been largely replaced by transistors in modern technology, audion tubes remain important in understanding the historical development of electronic devices.
Common Misspellings for AUDION
Etymology of AUDION
The word "audion" has its etymology rooted in the Latin word "audio", which means "I hear" or "I listen". "Audion" was originally the registered trademark name for one of the first vacuum tubes, invented by Lee de Forest in 1906. The term "audion" was subsequently used as a generic term for vacuum tubes and later for various types of electronic devices involving audio amplification.
