Hanning vs flat top window
WebThe illustrations below show the frequency-domain response of a single filter when using one of the available VSA windows. Click one of the windows in the following list to jump to that window: Window … WebThe Flattop window has a better amplitude accuracy in frequency domain compared to the Hanning window (Figure 9). The maximum amplitude error of a Flattop window is less than 0.01%. By contrast, the Hanning window maximum amplitude error is 15%.

Weblike about windows, but as we move on, you will come to agree that we have to use them. Both the Hanning and the Hamming windows indicate content at 15 and 17 Hz as well. The Kaiser Bessel window shows content in five bins, from 14 to 18 Hz. The Gauss window shows content from 13 to 19 Hz, and the flat-top window shows content from 12 to 20 … WebFor example, a Hanning window on a 0.5 second time record would have an ENBW of 3 Hz (1.5 Hz-sec/0.5 sec). Notice that the ENBW is slightly larger than the 3 dB bandwidth. The VSA's definition of resolution bandwidth (ResBW) is based on the normalized Equivalent Noise Bandwidth of the selected window type.
