- n. A highly evacuated electron tube containing an anode, a cathode, and a control grid.
- n. A thermionic valve containing an anode, a cathode, and a control grid; small changes to the charge on the grid control the flow from cathode to anode which makes amplification possible
- n. a thermionic vacuum tube having three electrodes; fluctuations of the charge on the grid control the flow from cathode to anode which makes amplification possible
“When I was a teenager learning about vacuum tubes, bias was a voltage applied to the grid of a triode.”
“When I was a teenager bias was a voltage applied to the grid of a triode (a kind of vacuum tube): a necessary thing, not a bad thing.”
“Then, almost simultaneously in 1911 and 1912, several engineers—de Forest among them—did manage to combine the triode with other existing circuit components to produce a workable amplifier.”
“And so, over a period of about four decades the triode vacuum tube became the key building element for a succession of technologies that produced both radio and modern computation.”
“He had been hoping that his triode tube would produce amplification of the signal, something highly desirable given the feebly transmitted radio signals of the day.”
“Adding one element to the diode makes it a triode, an extremely useful object that eventually would lead to electronics and computers.”
“Graphical Symbol in full simplified diode, indirectly heated duodiode, indirectly heated or triode, indirectly heated or duotriode with separated cathodes, indirectly heated, heating filament with central tapping, internal screening of the system tetrode pentode, suppressor grid connected with cathode triode - pentode triode - heptode (according to the circuit, the systems may be drawn left-and-right reversed) 1.10.”
“The present author has performed consulting work on one device which utilizes sound to convert the human body to a PPCM-triode and applies”
“We will attempt to produce a transformation of the Earth into a special triode, so that we may then introduce a relatively small "grid signal" and gate highly amplified energy from the Earth's interior self-powered cathode to an external plate load on the surface.”
“In effect, the Earth has been converted into a giant self-powered triode, and now any distant input site will function as both a grid input and a plate collector for the triode Earth.”
