| 11. | Listeners can listen using iTunes, Winamp, Audion, MusicMatch Jukebox, and a variety of other players.
|
| 12. | Thus, the Audion could not only detect and amplify radio signals, it could transmit them as well.
|
| 13. | His research and experimentation with the Audion moved radio reception beyond the crystal set and spark-gap transmitters.
|
| 14. | The grid Audion was the first device to amplify, albeit only slightly, the strength of received radio signals.
|
| 15. | Prior to the introduction of the Audion, radio receivers had used a variety of barretters, and crystal detectors.
|
| 16. | This design proved influential on vacuum tube production, and prompted De Forest to come up with a Tubular Audion.
|
| 17. | To give enough output power to drive a loudspeaker, 2 or 3 additional Audion stages were needed for audio amplification.
|
| 18. | By adjusting the tuning of this tuned circuit, Armstrong was able to dramatically increase the gain of the Audion amplifier.
|
| 19. | In 1906, Lee De Forest invented the Audion triode vacuum tube, an electronic valve that could amplify weak electrical signals.
|
| 20. | The program is also trivial : If the hotspot exceeds a threshold for too long a time, play an audion alarm.
