What are the magnitudes of the 8-point DFT samples of (a) the x:(n) = 9, 9, 9, 9, 9, 9, 9, 9 sequence (explain how you arrived at your solution)? (b) the xa(n) = 1, 0, 0, 0, 0, 0, 0, 0 sequence? (c) the xa(n) = 0, 1, 0, 0, 0, 0, 0, 0 sequence? Because the x3(n) sequence in Part (c) is merely a time-shifted version of the x2(n) sequence in Part (b), comment on the relationship of the X2(m) and X3(m)| DFT samples
