We can write the Fourier transform of x(n) in terms of magnitude and phase or real and imaginary components as follows: x(e") = |x(e/")| exp{j 0(ej")} = Xg(ej«) + jX,(ej«) %3D Assuming that x(n) is a real-valued signal, which of the following plots could be correct? Plot I: X,(e") Plot II: X,(el") `R 1 1 -27 27 -27 0 27 Plot III: |X(ej")| Plot IV: 0(ei") 1 1 -1 -27 -27 0 27
