A mixer tube used in a superheterodyne radio receiver. A pentagrid converter tube has five grids, a cathode, a plate, and a filament.
The incoming radio-frequency signal is applied to the signal grid, and a signal from a local oscillator is applied to the oscillator grid. The two signals mix and form two additional signals. The frequency of one is the sum of the two, and the frequency of the other is the difference between the two. The other three grids in the pentagrid tube are: two screen grids and one suppressor grid.

Industry:Aviation
A MOdulator-DEModulator used to connect two computers by way of telephone lines. Digital information from one computer is changed into tones for transmission over the phone lines. This is the function of the modulator. At the receiver end, the tones are changed back into digital information for the other computer to process. This is called demodulation.
Industry:Aviation
A moment divided by a constant, such as 10, 100, 1,000, or an even larger number. The use of a moment index allows weight and balance computations to be made using smaller numbers, and this decreases the chance for errors.
Industry:Aviation
A moment, or rotational force, that causes a body to rotate in a counterclockwise direction.
