This is the picture that we must remember; this may not come in one graph, so I try to
see. So, here let me see and try to draw this in a in a very complex fashion, this is my
spectrum here of wave and each of them represents a wave, this is my omega, this is my
s omega, these are all my eta’s.
And when I add them all up, (Refer Slide Time:29:56) this plus this plus this plus this,
this way I have got. See, please understand this, what we have done, this is how I have
done, see there is a irregular wave, this one is obtained by adding this one or you can
reverse it, there is a this is why I discuss before in irregular wave many times, there is an
irregular record can be broken down to regular record square of the amplitude, you put
them here, this is proportional to amplitude square, say amplitude square ok.
