NettetWindowing is essentially multiplying the waveform by a bell-shaped curve prior to analysis, improving the frequency resolution of the FFT output. The Hanning window is the most common window function for general-purpose FFT analysis. Other window functions may have different scallop loss or spectral leakage properties. Nettet25. okt. 2024 · The Hann window is a taper formed by using a raised cosine or sine-squared with ends that touch zero. Notes The Hann window is defined as w ( n) = 0.5 − 0.5 cos ( 2 π n M − 1) 0 ≤ n ≤ M − 1 The window was named for Julius von Hann, an Austrian meteorologist. It is also known as the Cosine Bell.
