The last page of the PDF shows how the DFS coefficient is related to the energy of a signal in a orthogonal signal set. What I don't understand is how is
Σgk[n]gm*[n] equal to Ek.δ [km], and how is the whole thing equal to CmEm?
Notation: Ek is the energy of gk[n], Em is the energy of gm[n]. cm and ck are the mth and kth discrete fourier series coefficient.
