“硬球”相关时间序列的频谱分析

An Analysis of the Time-Sequence of a “Hard Ball” Correlation

本文以教室中噪声为基本模型 ,讨论了时间相关序列的频谱 ,指出非线性的时间相关会使时间序列呈现出大致的周期性 .

Based on the noise in a classroom, this paper has discussed the frequency spectrum of a time sequence, pointing out that non linear correlation makes time sequence to show itself a rough periodicity. The theoretical result is similar to the reality.
