. (Difficulty: ★★*) Consider the 2D signal I of size 16 × 16: I Շ Ա. 15 10 5 ob 0 5 n 1 10 15 Full (blue) circles correspond to points where the signal has the value 1, otherwise its value is 0. From the 2D signals I₁, . . . , I6 given below, check those that have the same magnitude 2D-DFT spectrum as the 2D signal I.
