What is the effect of the Hanning window?
The Hanning window is a compromise between the Flat Top and Rectangular windows. It helps to maintain the amplitude of a signal while at the same time maintaining frequency resolution. This window can have up to a 16% amplitude error if the signal is not periodic.
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.
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.
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.
