So, you see I have this, break it down to these pieces. What is this breaking down? This
is basically this breaking down is algebra pure, you know what is this going from here to
here? This is actually response in regular waves. A regular wave given what is the
output, what is this to this? Algebra, just adding them up. So, you see getting here to here
is not so tough, it is actually in your mind, very simple because if I can break it down to
this pieces which I have done in a spectrum analysis, you know spectrum, we say that
actually it is nothing, but this the broken pieces, then I can actually go from here to there.
