| 摘 要： | 文章讨论了采用ARMA模型实现随机激励谱的问题,分析了模型阶数对ARMA谱的影响。论文表明,对给定的目标谱,存在一最低阶的ARMA模型。当阶数高于最低阶数时,阶数变化的影响很小。

| Abstract: | This paper deals with the realization of the spectrum of random exitations with the aid of ARMA model.The influence of the model order on the ARMA spectrum is studied. It is shown that an ARMA model of minimum order exists for a given target spectrum. With the order higher than the minimum one, changes in the order are usually of little consequence. |
