Which is better Hamming or Hanning window?
Hamming and Hanning
Between the two, the Hamming window does a better job of cancelling the nearest side lobe, but a poorer job of cancelling the rest. Due to their speed and good-enough noise performance, these windows have historically seen use in voice communications.
What is the difference between Hamming and rectangular window?
It is demonstrated that filter design using hamming window is comparatively better than rectangular and hanning window though the components required for all of the windowing technique are same, hamming shows higher stability. The stability is shown with the help of magnitude and phase spectrum of each window.
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 advantage of Hamming window?
The Hanning window is usually a good choice. The main advantage of controlling the leakage is an increase in the dynamic range of the analysis, as leakage may swamp signal components of close frequencies and much smaller magnitudes.
