whereas in the DFT, we see frequencies with values like 228, 204 etc. which are all > 100. If you look at those additional frequencies, you will uncover a pattern i.e. 228=288–60, 204=288–84 and so on. If the frequency v has amplitude of A, then the frequency N-v also has amplitude of A, where N is
