No power, mode, or frequency controls are present.
12.
In 1984 the group again changed its name to the IEEE Ultrasonics, Ferroelectrics and Frequency Control Society.
13.
FEI Time / frequency control 227.28 64.
14.
They are used in lasers for Q-switching, telecommunications for signal modulation, and in spectroscopy for frequency control.
15.
Lasers have extremely accurate and stable frequency control, and the light they emit interacts strongly with free electrons.
16.
Some generator units, especially in isolated systems, operate with isochronous frequency control, maintaining constant system frequency independent of load.
17.
This effect is used to good advantage for automatic frequency control in receivers, and in frequency modulation for transmitters.
18.
Wind turbines with variable-speed generators have the potential to add inertia to the grid and assist in frequency control.
19.
They have a few ( widely spaced ) frequency ranges, and relatively wide-range continuous frequency control within a given range.
20.
Somewhat limited in features, they were designed for AM phone operation only and frequency control was crystal controlled on transmit.
