Let X (e^jω) denote the Fourier transform of the signal x[n] shown in Figure P2.55. Perform the following calculations without explicitly evaluating X (e^jω):

(e) Determine and sketch the signal whose Fourier transform is X (e−^jω).

(f) Determine and sketch the signal whose Fourier transform is Re{X(e^jω)}.
