Signal loss is the reduction of a signal that occurs in a medium as a function of the physical length of the channel. This is known as: a. degradation.
b. attenuation.
c. frequency degradation.
d. amplitude degradation.

B) Attenuation

Explanation:

Attenuation can be regarded as the loss of signal strength which could be as a result of both external and internal factors. This loss of signal strength could occur in networking cables as well as other connections. Attenuation is a loss in energy, because as signal travels, its strength decreases as a a result of distance it covers, this loss of energy is due to the signal trying to overcome the resistance at the medium. One of the main the causes of attenuation is When there is Extra noise on available networks, networks such as electrical current as well as radio waves. It should be noted that attenuation is Signal loss which is the reduction of a signal that occurs in a medium as a function of the physical length of the channel.

Singnal attenuation can taken care of by using lower loss materials with high cost, instead of making of PCB routing length reduction. Amplifiers can also be engaged in amplifying attenuated signal to get back the original signal, this will compensate the loss.

Attenuation can be measured in decibels(dB), this gives the measurement of relative strengths of one signal at two different point or measurement of two signals.

answer:

i lost in getting someone back.

i learned that people are really two-faced and no matter how angelic someone appears they always have a devil side and that you cant trust anyone anymore no matter how dear they are to you.

if your wondering who it waz it waz mah still miss her tho

~batmans wife dun dun

answer:

put more,
