Does Fiber Optic lines are immune from crosstalk?
Yes.
What will happen if field winding of attenuator gets open?
The motor will be unable to function. The magnetic field will no longer exist due to the open short and there will be no latent or motive power.
What is the difference between crosstalk and attenuation?
well both attenuation and crosstalk are used extensively in communications especially in data communications. the difference between the two is how they both affect signal or intelligence run across a media from a point of origin to a destination. attenuation is the degradation of the signal due to various reasons such as noise introduction, lossy media, distance, and the like. crosstalk however is the interference of signal to an adjacent one whereby affecting the signal's essence. usually cause by radiation of electromagnetic induction run through a media usually copper. usually a high frequency transmitted over a wired media causes crosstalks to adjacent ones if proper shielding is neglected, however attenuation may also occur if the signal is projected towards a lossy media over a long distance and with the presence of noise. both are always introduce in a communication environment but have their differences where one degrades while the other affects signal. A UTP network cable consists of four 'pairs' of wires. The two wires in each pair are twisted around eachother to help provide immunity to interference. If we consider a signal being sent down one pair in isolation, then the attenuation of the cable is the degree to which the signal gets reduced in magnitude as it travels down the cable and comes out the other end. As mentioned, this causes degradation of the signal because as you get less and less signal then the noise, interference etc also present on the cable becomes more significant and can corrupt the data. Crosstalk is the extent to which a signal sent down one pair of the cable also appears on another pair. The cross-coupling occurs by electromagnetic induction, and the 'unwanted' signal due to the crosstalk also contributes to the noise on the pair that competes with the wanted signal. The twisting of the pairs aims to reduce the induction, lowering both the crosstalk between the pairs within the cable and interference induced from outside. What determines the attenuation is a little more complex, but basically it's to do with how the construction of the cable matches the frequency being used. The higher the data rate (anf hence frequency of the signal) the 'better' the cable has to be and the tigher the manufacturing tolerances
How do tosters work?
they just work they just work,work,work

the work a machine does is the work outputwhat it takes to do the work is the work inputSources;The_work_that_the_simple_machine_does_is_called_the_work
Attenuators are the opposite of a what?
An attenuator is the opposite of an amplifier. An attenuator is used for reducing the power of a signal. An attenuator is able to do this without modifying the waveform of the signal.
What are the Types of material used in attenuator?
different types of material used in attenuator
What is the function of an attenuator in cro?
An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. attenuator just decrease its amplitude and the attenuator you can take it as a opposite of amplifier. Amplifier just modifies the input signal gives amplified output signal
What is meant by homowavelength?
homowavelength crosstalk is a crosstalk that occur on a single wavelength.
What are attenuators?
attenuator (disambiguation)An attenuator has three distinct meanings:* attenuator (electronics) is an electronic device that reduces the amplitude of a signal* attenuator (genetics) refers to specific regulatory sequence transcribed into RNA* impact attenuators are used on highways as a crumple zone in case of a car crash.Above retrieved from Answers.comViper1
What is the other name of attenuator?
Randy
What is the function of attenuator unit?
Nothing
What is the opposite to an amplifier?
An attenuator.
Why An attenuator is used with TWT?
To prevent saturation
What are the ratings and certificates for Crosstalk - 1982?
Crosstalk - 1982 is rated/received certificates of: Australia:M Iceland:12
How can you reduce crosstalk?
Reducing crosstalk depends on where the crosstalk is occurring. In adjacent channels on something like, say, a microwave link, polarizing the signals on adjacent channels alternately works pretty well. There are other ways, and lots of other places where crosstalk can appear. Just one was cited.
Which procedure is used to reduce the effect of crosstalk in copper cables?
designing a cable infrastructure to avoid crosstalk interference
