(1) Radiodifusin: is the transmission ofsignals by modulating waveelectromagnetic.

(2) VHF:generally usedforsystemsof land navigation and radioamadorismo.

(3) SHF:the sper-alta frequency (SHF) is a band radiofrequency (RF) bandinthe range 3-30 GHz SHF and EHF are known asmicrowave bands and theirwavelengths are short enough t o be reproduced by directional antennassignupand wave guides

(4) Am:moderate extent

(5) Fm:moderate frequency

(6) Television by satlite: is a methodofconsistent to bounce signaltelevision emittedfrom a point on the Earth in a communicationssatellitetelevision broadcast

(7) CATV: (Community Antenna Television - cable television) . Servicewhich offers television tosubscribing homesimage transfer


2/6

(8) Cable modem:is a special modemdesigned tomodulate the signaldata over cable television infrastructure

(9) Fiber optics:sensor tomeasure voltages, temperature pressure aswell asotherparameters

(10) Tube Holgado:isolates external mechanical forces engagedon cableFiber

(11) Voice:dramatic load

(12) Word: conceptual image

(13) SONIDO:physical context

(14) MUSICA: transmitsfeelings

(15) Mute: valorisation

(16) HF: transmits electromagnetic waves that propagate .is very distantsignal say travel in a straight line

(17) UHF: broadcast digital terrestrial television, cable television via

cellphone.

(18) Broadband:divides the bandwidth in frequencies to transmit the samesignal wavesinformation


3/6

(19) BANDA base:emits the signal without alteringit not modulated affectssignal transmissions both receivers

(20) GPS: browser GPS satellite position ofan object that determines the

world

(21) COAXIAL:is a cable used to transport signals high frequency that hastwodrivers centrally located central one called live responsible forcarryinginformation andone external called armor that serves asreferenced land and return ofthe stream.

(22) TDT:is a technology to replace analogue TV convencionale.la imagesound and additional services are transformedinto TV digital that isdisseminateddare waves terrestrial.

(23) PSK: known asdisplacement due tosudden satellite digital modulator.

(24) Header:is the centerof the network group, and treat various contentwill be transmitting network

(25) Ultraviolet:is the length ofwavesmuch more short

(26) X RAYSdesignates an electromagnetic radiation layers through bodies.

(27) RAYS gama:is a type ofelectromagnetic radiation , and thereforeconsistsofphotons,usually produced by radioactive elementsorsubatmicosprocesses as the annihilation ofa pairofPositron - electron

(28) Beams T:thisinfrared light long wavelength might have a host ofpossible applications, but until recently, had been impossible toproducebeamssufficiently strong andstable

(29) Spectrum ELECTROMAGNTICO:b12 energy electromagnetic waves setdistribution. Referring to an object is called the electromagnetic spectrum or simply

spectrum electromagnetic radiation emitting (emission spectrum) or absorbs

(absorption spectrum) a substance. This radiation is used to identify the substance

similar to a fingerprint

(30) Length of A wave:is, asits name implies, a length. In other words; adistance. A wave length is the distance of the wave in the interval of timebetween two consecutive one ofitspropertiesmaximum

(31) Speed of light:empty is by definition a universal constant value exactlym/s23 (usually approximate 310 8m/s), which is 9, 4610 15m/ year;the secondfigure isused todefine the interval called light year.

(32) DIMMER:signal, whether this acoustic, electrical oroptical lossofpowersuffered by it topass through any meansof transmission

(33) Circuitis an electrical network (interconnection of twoormorecomponentssuch as resistors,inductors, capacitors,sources,switchesandsemiconductor) containing at least a closedpa th

(34) Resistance power,symbolizedusually asR,is the difficulty oropposition that presents a body to the passage ofan electric current, tomove through. SI

(35) O coilINDUCTOR:is a passive an electrical circuit which,due to thephenomenon of choke,storing energy in the formofmagnetic fieldcomponent

(36) Condensador:in electricity and electronics, a capacitor(capacitancein English) is a device which stores electricity,is a passive component. Isformed by a pairof conductingsurfacesin a position to influence total


5/6

(37) Fuente:in electricity meanssource to element active which is capableofgenerating a potential difference (d. d. p.) between its terminalsorprovide an electrical current. Follows a possible classification ofelectricalsources

(38) Switch electrical:is a device used todivert or breaking the flow ofanelectric current. In the modern world applications are innumerable,rangingfrom a simple switch that turnsoffor high a lightbulb,until acomplex selector transfermultiple layers automatic computer-controlled.

(39) Semiconductor: usually are typically encapsulatedin a materialceramic,metal orplastic, andfinishedin twoormore terminalsormetalPIN. Are designed to be connected between them, normally by meansof

welding, a printed circuit, toform the above circuit

(40) The CROSSTALK:for twistedpair cablesusually occursdue tomagnetic circuitsdisturbed anddisturbingitemsor as a result ofimbalances between the threadsof admittance couplingsboth circuits.

(41) Signal ANALGICA:is a type ofsignal generated by some type ofelectromagnetic phenomenon and that is representable by a continuousfunction that its amplitude andperiod (representing a data information) isvariable dependingon the time

(42) Periodo:an oscillation or wave period (T) is the time elapsedbetween two equivalent pointsoscillation or cycle. Is the minimumperiodthat separates twomomentsin which the systemis exactly the sameState:same positions,same speeds,same amplitude

(43) Extent:oscillatory motion, wave or electromagnetic signal is a measureofthe maximumdisplacement orotherphysical magnitude variesperiodically or quasiperiodic variation in time. Thisis the maximumdistance between the point further away a wave and a balance ormedium

(44) ONDA Nakashima:is a longitudinal wave where the sound travels. Ifspreadsin an elastic medium and continuous builds a local variation ofpressure ordensity, which airson periodic spherical wave or quasiperiodic

(45) ONDA ESFRICA:in physical,is that wave three-dimensional spreadat the same speedin all directions. It is calledspherical wave becausetheir wave fronts are concentric spheres, whose centers coincide with theposition of the source ofdisturbance.

(46) Speed:is a physical scale vector expressing an object displacement perunit time character

(47) Unit of time:timeis createdphysical scale formeasuring the interval inwhich an orderedseriesofevents happen. The time commonly usedsystemis the Gregorian calendar andisusedin both systems, theInternational system and the Anglo-Saxon systemofunits .

(48) Force:is a physical magnitude that measures the intensity of theexchange ofmomentum between twoparticlesorparticlessystems (inparticle physics language spoken interaction )

(49) Electrical potential:point is work that must take an electrical force tomove a loadpositive qfrom the reference to that point,divided by loadtest drive
