Read each part of this problem carefully to note the differences among parts.
(a) Consider the signal

Plot |X16[k]| for 0 ≤ k ≤ 15 without explicitly evaluating the DFT expression. You will not be able to find all values of |X16[k]| by inspection as in parts (a) and (b), but you should be able to find some of the values exactly. Plot all the values you know exactly with a solid circle, and plot estimates of the other values with an open circle.
