WebIn signal processing and statistics, a window function (also known as an apodization function or tapering function) is a mathematical function that is zero-valued outside of some chosen interval, normally symmetric around the middle of the interval, usually near a maximum in the middle, and usually tapering away from the middle.Mathematically, … WebThe coherent gain of the 20-point Hann window in this example is 0.475. With larger Hann windows, the coherent gain will approach 0.5. Similar "spectral leakage" also occurs when the discrete Fourier transform is computed at points between the actual transform components.
