We investigate the connection between the interaction energy function of ΨH and the cross-power spectral density (CPSD) of two complex valued signals. In particular, this link permits to use this operator for estimating the CPSD. We illustrate the interest of ΨH as a similarity between a ...
Power spectral and cross-spectral studies of atmospheric electrical parameters for different months of the year are presented. The data represent fair weather conditions and the frequency range is from 0.01 to 0.3 cph. The analysis shows spectral peaks in the atmospheric electric parameters for frequen...
此提交提供了使用 Welch 方法计算功率谱密度 (PSD) 的可能性。 该文件基于使用信号处理工具箱的 Matlab 实现。 我排除了计算机密间隔的可能性。 如果需要,请发表评论,我会更新必要的依赖项。 WelchPowerSpectralDensity.m 文件的标题中给出了一个使用示例。 另外两个文件 Hann.m 和 Hamming.m 提供了算法所需的...

The detailed study of the cross-spectral power density phase versus frequency variation shows that on some occasions a reamplification process takes place at each bounce of the wave, but only on one of the two trajectories. 展开 关键词: classical and quantum mechanics, general physics ...
