`R
`
`radar A system that detects distant ob(cid:173)
`jects by measuring the deflection of micro(cid:173)
`wave frequencies, used, for example, to
`provide information about the movement
`of aircraft, ships or vehicles.
`
`radio frequencies The spectrum of fre(cid:173)
`quencies used for radio transmission and
`generally considered to be within the range
`from 20 kHz to 3 GHz. c:> article on
`electromagnetic waves.
`
`radio frequency carrier wave A radio fre(cid:173)
`quency signal used to carry another signal
`imprinted upon it by the techniques of
`modulation.
`
`radio frequency signal Any signal falling
`within the radio frequency spectrum (20
`kHz to 3 GHz) and used to radiate infor(cid:173)
`mation through space. c:> article on electro(cid:173)
`magnetic waves.
`
`30 kHz to 300 kHz
`
`radio frequency spectrum The range of
`electromagnetic waves associated with
`radio and television broadcasting, includ(cid:173)
`ing transmission in the following band(cid:173)
`widths:
`low frequency
`(LF)
`medium frequency
`(MF)
`high frequency (HF)
`very high frequency
`(VHF)
`ultra high frequency
`300 MHz to 3 GHz
`(UHF)
`This spectrum covers the present range of
`frequencies used for commercial and mili(cid:173)
`tary/civil communications.
`
`300 kHz to 3 MHz
`3 MHz to 30 MHz
`30 MHz to 300

`
`radio receiver A device which can be
`tuned to receive radio frequency signals and
`to detect sound signals carried in the broad(cid:173)
`cast radio signal for audible presentation to
`listeners.

`
`radio signal Same as radio frequenc
`signal.
`Y
`
`radio transmission A form of te/ec0111_
`munication in which message signals ar
`radiated as energy in the form of rad·e
`waves. Examples of radio transmissi~o
`include sound and television public broadn
`cast systems, established to serve a Pa •
`:~
`ticular geographic area, as well
`directional radio systems designed
`to
`provide a channel for point-to-point com.
`munication.
`
`radio transmitter A device capable of
`capturing signals representing sound or
`light and converting them by a process of
`modulation into a form suitable for trans.
`mission as electromagnetic waves in the
`radio frequency spectrum.
`
`radio waves A range of electromagnetic
`waves, in the frequency spectrum from 20
`kHz to 3 GHz, which are suitable for carry.
`ing signals across space.
`
`radiometry The measurement of Ii
`energy from a source, irrespective
`human factors involving the perception
`light. Studies concerned with considerati
`of the human factors are known as pho
`me try.
`RAM c:> random access memory.
`
`random access memory (RAM) A type
`storage device used in computers tor
`·
`information directly with very short
`times measured in milliseconds. An
`ticular retrieval operation will prod
`formation within a more or Jess co
`access time, regardless of the last loc.a
`addressed. Magnetic disc storage is
`example of such a storage medium,
`magnetic tape is not a random a
`memory medium. ~main memory.
