A radar display on which slant range is shown as the distance along a horizontal trace .
(1) Dissipation of radio or sound waves as they interact with matter. (2) The absorbing of light waves without reflection or refraction .
An instrument used to measure audio frequencies .
An electrode charged several thousand volts positive and used to accelerate
electrons toward the front of a cathode-ray tube .
A servosystem that controls the acceleration (rate of change in velocity) of a load .
A device that measures the acceleration to which it is subjected and develops a
signal proportional to it .
An impurity which, when added to a semiconductor, accepts one electron from
a neighboring atom and creates a hole in the lattice structure of the crystal. Also called TRIVALENT
A very small tube with closely spaced electrodes and no base. The tube is connected to its circuits by short wire pins that are sealed in a glass or ceramic envelope. The acorn tube is used in low-power uhf circuits .
The science of sound .
Operational phase of a fire-control or track radar during which the radar system searches a small volume of space in a prearranged pattern .
