WebThe Hanning window is defined as. w(n) = 0.5 − 0.5cos( 2πn M − 1) 0 ≤ n ≤ M − 1. 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. Most references to the Hanning ... WebConsider how the Hanning window is defined: 0.5 - 0.5 * cos (n*2*Pi/ (N-1)) By this definition, it has a gain of 0.5, which is simply the average value of the coefficients. By contrast, Flattop windows, as defined, have unity gain, presumably by design.
