What is a Hamming window used for?
With what I know about sound and quick research, it appears that Hamming Window is here to minimize the signal side lobe (unwanted radiation). Thus improving the quality or harmonics of the sound.
Why the use of Hamming window can reduce the problem of using rectangular window?
By using a window function other than the rectangular one there is less of the sidelobes compared to the main lobe, so less artificial long-distance spread making the result cleaner and better suited for frequency-selective analysis.
What is the equation for Hamming window filter?
The following equation generates the coefficients of a Hamming window: w ( n ) = 0.54 − 0.46 cos ( 2 π n N ) , 0 ≤ n ≤ N .
What is the difference between Hann and Hamming window?
Hamming and Hanning
The difference between them is that the Hanning window touches zero at both ends, removing any discontinuity. The Hamming window stops just shy of zero, meaning that the signal will still have a slight discontinuity.
