Let x[n] = cos(2πn/5) and v[n] be the sequence obtained by applying a 32-point rectangular window to x[n] before computing V(e^jω). Sketch |V(e^jω) for –π ≤ ω ≤ π, labeling the frequencies of all peaks and the first nulls on either side of the peak. In addition, label the amplitudes of the peaks and the strongest side lobe of each peak.
