Electronic engineering

common-carrier fixed station

Engineering; Electronic engineering

A fixed radio station that provides public service.

absorption modulation

Engineering; Electronic engineering

Amplitude modulation of a transmitter or oscillator by means of an audio-frequency- actuated absorber circuit. In its simplest form, the modulator consists of a few turns of wire coupled to the ...

coma lobes

Engineering; Electronic engineering

An aberration in the radiation or response pattern of a dish antenna that occurs when the radiating element is not exactly at the focal point of the reflector. When the directional

coma

Engineering; Electronic engineering

An aberration that causes the beam spot on the screen of a cathode-ray tube to resemble a comet.

biological shield

Engineering; Electronic engineering

An absorbent shield that blocks or attenuates ionizing radiation to protect personnel working near radioactive materials.

An absorption wavemeter whose adjustable element is a tunable resonant cavity into which radio-frequency (RF) energy is injected through a waveguide or coaxial cable. Such an instrument is useful at ...

capacitive attenuator

Engineering; Electronic engineering

An ac attenuator whose elements are capacitors in any desired combination of fixed and/or variable units. The desired attenuation is afforded by the capacitance ratio.
