WebJun 12, 2024 · When the PicoScope FFT spectrum analyzer is applied to an input signal, there is the option of selecting a window function to reduce spectral leakage from one bin to another. A general discussion of this problem is provided in this paper, which concentrates on power spectra, but the whole idea of spectral leakage applies to any FFT calculation ... Web'symmetric' — Use this option when using windows for filter design. 'periodic' — This option is useful for spectral analysis because it enables a windowed signal to have the perfect periodic extension implicit in the …

窓関数（まどかんすう、英: window function）とは、ある有限区間（台）以外で0となる関数である。 ある関数や信号（データ）に窓関数が掛け合わせられると、区間外は0になり、有限区間内だけが残るので、無限回の計算が不要になり数値解析が容易になる。窓関数は、データから成分を抽出するアルゴリズムの中核に当たり、スペクトル分析、フィルタ・デザインや、音声圧縮に応用される。窓関数を単に窓 (window) ともいい、データに窓関数を掛け合わせることを窓 … WebAfter much search online, it looks like I’d need to use the Hamming Distance for that, or its equivalent: find the Hamming Weight to the result of an XOR operation between two words.
