WebThe scalloping loss with the Hann window is -1.28 dB. Thus, the scalloping loss is a measure of the shape of the main lobe of the DFT of the window. This is, of course, a computation of the scalloping loss at half a component of the DFT after some randomly chosen frequency for a very short window. With the formula above and for larger … WebWhen b = 0, the Kaiser window becomes a rectangular window (no tapering). As b rises, tapering increases, and the main lobe width increases and sideband attenuation increases. The exact formula for the Kaiser window is complicated. Figure 2 shows Kaiser windows with b=3, 5, and 10. Figure 2. Kaiser window comparison.
