For high data rate ( data transfer speed ) the bandwidth of the signal carrying system should be high. Because a high data rate means a high frequency ( square ) wave actually such a wave consists of a large number of waves having a range of frequencies Fourier analysis) so to get a distortion less transmission the bandwidth should be high.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
