against you can say measure of height this side for the same signal. So, it is correlating both the things. Earlier, what happened, I only said I have so many heights occurring so many times, etcetera. But, here these signals – I can now break it down to say how many frequencies exist of what height or what is the combination; that means, this irregular spectrum consists of what regular waves. Remember one thing – if I say there is a wave of omega 1 of frequency A 1, like of amplitude A 1; let us say this is omega 1 means 100 meters long wave; of amplitude A 1 means 5 meters. What I am saying effectively is that I have in this signal one component of 100 meters long wave of height 5 meters or five 1 meter waves, because five 1 meter wave also gives me 5 meter wave for the same length. So, here we are doing that. Remember, why I am saying this five 1 meter wave? Because earlier, what happened, let us say in a signal I broke it down 5 meter occurred once, twice, three times, etcetera. So, I say 5 meter occurred four times; 3 meter occurred one time, etcetera. But, here the time part is not taken. If 5 meter occurred four times, then all get embedded as one number, lump number. So, this is what the concept behind sea spectrum is. This of course, any signal as I mentioned before, at the very beginning, can be Fourier analyzed and you can always plot this A i square (
Length means period means frequency. So, you see, I could get frequency this side
