矩形脉冲信号 meaning in English
rectangular pulse signal
Examples
- Based on the method , this dissertation deals with several kinds of signals including cosine wave ( cw ) , linear frequency modulated ( lfm ) and multi - component signal , furthermore the systematic comparison of estimation effect among cwt and several other usual methods as well cramer - rao bound ( crb ) is given
基于上述方法，文中分别对单频矩形脉冲信号、线性调频脉冲信号以及多分量信号进行了瞬时频率估计，并与其他几种常用瞬时频率估计方法的性能以及crb进行了系统比较。 - Second , i transform seismic - electrical data and volcano data worldwide from 1991 to 1999 to appropriate statistic models and analyze them by using the theories of random process and correlation . the results of the study testify that it is correlative between the seismic - electrical abnormal rectangle pulsation signals and volcano eruptions . so the study is a useful exploration for which whether we can monitor and observe worldwide volcanic activity in the whole
接下来应用随机过程与相关理论的知识，以1991年1月1日至1999年12月31日为统计时间段，以北京工业大学地震研究所南北方向地电脉冲仪所记录到的地电异常矩形脉冲信号和全球范围内的火山喷发事件为研究对象；抽取适合分析、又具物理意义的多个统计模型；并对信号模型与喷发模型间进行了详尽的相关性分析。
