`

`skinner-slave
`
`depth of penetration of electric currents
`into a conductor decreases as the frequen(cid:173)
`cy increases. 4. A characteristic of current
`in a conductor whereby as the frequency
`increases more and more current flows
`near the conductor surface and less at the
`center.
`skinner-A wire brought out at the end of
`a cable prepared for soldering
`to a
`terminal.
`skinning- Peeling the insulation from a
`wire.
`skin tracking - Radar tracking of an
`object without the aid of a beacon or other
`signal device on board the object.
`skip-!. A digital-computer instruction to
`proceed to the next insuucrion. 2. In a
`computer, a "blank" instruction. 3. To
`ignore one or more of the instructions in a
`sequence. 4. Term referring to J7ropaga(cid:173)
`tion of radio signals over considerable dis(cid:173)
`tances due to reflection back to earth from
`the iooos phere.
`skip distance- The distance separating
`two points on the earth between which
`radio waves are transmitted by reflection
`from the ionized layers of the ionosphere.
`skip fading-Fading due to fluctuations
`of ionization density at the place in the
`ionosphere where the wave is reflected,
`which causes the skip distance to increase
`or decrease.
`skip-if-set instructions-In computers,
`a class of instructions in which provision
`is made for examining particular logic
`conditions. Usually they are used in con(cid:173)
`junction with a jump (branch) instruc(cid:173)
`tion. For example, a
`skip-if-word(cid:173)
`register-ready instruction would allow
`the program to check for a ready condi(cid:173)
`tion of the word register and then permit
`the program to continue along one of two
`different paths, depending on the condi(cid:173)
`tion of the word register.
`skip keying- The reduction of the radar
`pulse-repetition frequency to a submulti(cid:173)
`ple of that normally used, to reduce the
`mutual interference between radars or to
`increase the length of the radar time base.
`skip zone -Also called zone silence. A
`ring-shaped space or region within the
`transmission range wherein signals from a
`transmitter are not received. It is the dis(cid:173)
`tance between the farthest point reached
`by the ground wave and nearest point at
`which the refracted sky waves come back
`to earth.
`skirt selectivity-A measure of the reso(cid:173)
`lution capability of spectrum analyzer
`when displaying signals of unequal ampli(cid:173)
`tude. A unit of measure would be the
`bandwidth at some level below the 6-dB(cid:173)
`down points.
`sky error- See Ionospheric Error.
`sky b.ook-Amareur term for antenna.
`sky noise- I. Noise produced by radio
`energy form stars. 2. Background micro-
`
`932
`
`wave radiation coming from deep space.
`It can be a noise source for dish antennas
`and sets a lower boundary for the possible
`noise temperature of any dish antenna of
`approximately 16 to 20 K.
`SKU - Stockkeeping unit. Abbreviation
`used in many computer reports to define
`an individual stock item.
`sky wave - See Ionospheric Wave and
`Indirect Wave.
`sky-wave correction- In navigation, a
`correction
`for
`sky-wave propagation
`errors applied to measured positional
`data. The amount of the correction is
`established on the basis of an assumed
`position and on
`the height of the
`ionosphere.
`In sky(cid:173)
`sky-wave station error -
`wave- synchronized loran,
`the station(cid:173)
`synchronization error due to the effect of
`the ionosphere on the synchronizing sig(cid:173)
`nal transmitted from one station to the
`other.
`sky-wave-synchronization loran -A
`loran system
`in which
`the range
`is
`extended by using ionosphere-reflected
`signals for synchronizing the two ground
`stations.
`sky-wave transmission delay - The
`longer time taken by a transmitted pulse
`when carried by sky waves reflected once
`from the E-layer, compared with the
`same pulse carried by ground waves.
`slab - A relatively thick crystal from
`which blanks are cut.
`slab line -A double-slotted coaxial line
`the outer shield of which has been
`unwrapped and extended to infinity in
`both directions so that the resulting con(cid:173)
`figuration is a cylindrical conductor be(cid:173)
`tween two parallel conductors.
`slab wafer - A slice of semiconductor
`material
`that has straight edges, as
`opposed to a conventional rounded wafer
`that has 21 percent less area than a square
`with comparable dimensions.
`slant range- I. In radar, the line-of-sight
`distance from the measuring point to the
`target, particularly an aerial target. 2.
`Line-of-sight distance between two points
`not at the same elevation.
`slap-back - An echo effect that is pro(cid:173)
`duced where the original signal reappears
`as distinct echoes that decay in level each
`time they appear. One way of creating
`slap-back is to feed the output signal from
`the play head back into the record head,
`at a slightly lower level. For example, if
`the sound "Ia'' is originally fed to the
`recorder,
`then "Ia-la-Ia .. .Ia" will be
`heard, with each "Ia" slightly lower in
`level until the signal fades away.
`slave- I. A component in a system that
`does not act independently, but only
`under the control of another similar com(cid:173)
`ponent. 2. A device that follows an order
`given by a master remote control.
