Let x[n] be a discrete-time signal whose Ωspectrum you wish to estimate using a windowed DFT. You are required to obtain a frequency resolution of at least π/25 and are also required to use a window length N = 256. A safe estimate of the frequency resolution of a spectral estimate is the main-lobe width of the window used. Which of the windows in Table 7.2 will satisfy the criteria given for frequency resolution?
