Question:

Two finite-length sequences x[n] and x1[n] are shown in Figure. The DFTs of these sequences, X[k] and X1[k], respectively, are related by equation?

X1[k] = X[k]e ?j (2?km/6),

where m is an unknown constant. Can you determine a value of m consistent with Figure? Is so, justify your answer. If not, find another choice of m consistent with the information given.
