What is the relationship between gain and bandwidth?

The basic relationship is that the two together form some kind of constant wherein you cannot have more of one without giving up some of the other. Want more gain? You'll have to work with a narrower bandwidth.

Want more bandwidth? You will have to sacrifice some gain to get it.

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.
