Hanning window
基本例句
海宁窗
An explicit specturum correction approach is proposed to short records weighted by aHanning window.针对短记录加汉宁窗,给出了一种显式频谱校正方法,它利用局部谱峰附近的三条谱线。
Using simulated single-frequency wavefront,PSD values before and after applyingHanning windowwere computed and a modification factor was deduced using theory of Fourier transform.通过对模拟的单一频率波前加窗前后的功率谱密度的理论计算,由傅里叶变换性质推导出了修正因子,并对波前频率与修正因子的关系进行了理论研究。
It shows that under certain measurement errors and certain frequency scope, a constant, 8/3 or 64/9 is effective to modify one-dimensional or two-dimensional PSD value after applyingHanning window.结果表明，在一定的波前频率及误差范围内，对加汉宁窗后1维功率谱密度的计算结果乘上一个常量8/3即可实现简单有效地修正。
Hanning windowed interpolation harmonic analysis algorithm and high-order sine fitting algorithm are the two effective algorithms for dielectric loss angle measurement.加汉宁窗谐波分析法和高阶正弦拟合法是介损角测量的两种有效算法,对两种算法的分析和比较有利于它们在实际中的应用。 |
