In this chapter, we compute several parameters of a window that are useful in choosing a suitable window for particular applications, such as power spectral estimation via discrete Fourier transform (DFT) and the design of FIR digital filters. A comprehensive comparison of the windows that were introduced in Chapter 3 is made based on the computed parameters. All the parameters listed are computed using the properties of windows in the continuous-time-domain.
The leakage that occurs in spectral estimation (via DFT) due to the prominent side lobes of the spectral window obviously degrades the accuracy of the results. Windows are weighting functions applied to the finite observation data ...
