Is Hann and Hanning window same?
The Hanning was named for Julius von Hann, an Austrian meteorologist. It is also known as the Cosine Bell. Some authors prefer that it be called a Hann window, to help avoid confusion with the very similar Hamming window.
Why use a Hanning window?
Hanning is the most commonly used window function for random signals because it provides good frequency resolution and leakage protection with fair amplitude accuracy.
What is the difference between Hamming and Hanning 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.
Why is a hanning window better than a rectangular window?
In most biomedical applications, any one of the windows considered above, except the rectangular (no taper) window, will give acceptable results. The Hamming window is preferred by many due to its relatively narrow main lobe width and good attenuation of the first few side lobes.
