四、应用例证本章将简要地概述尤尔一一沃尔克法和伯格法的可能性。正如我们在前一章第三节中看到的那样,这些方法都很相似,并取决于系数a_i的数量M。如第二章所述,用这些系数能够计算出谱密度(2.61),其精确度随M的大小而变化。为了验证这些方法,我们将应用这些方法得到的谱密度与库里一吐克(Cooley-Tukey)算法获得的谱密度进行了比较,后一种算法是很精确的。为此,我们取了在蒙特科邦获得的干扰波记录中的三段。第40道的记录时间为790—
IV. APPLICATION EXAMPLES This chapter gives a brief overview of the possibilities of Yule-Volcker and Berg. As we saw in the previous section, Section III, these methods are very similar and depend on the number M of coefficients a_i. As described in Chapter 2, the spectral density (2.61) can be calculated using these coefficients, the accuracy of which varies with the size of M. To verify these methods, we compare the spectral densities obtained using these methods with the spectral densities obtained from the Cooley-Tukey algorithm, which is very accurate. To this end, we have taken three passages from the interference wave record obtained at Monte-d. The 40th record time is 790-
