地震记录道的振幅包络、瞬时相位、瞬时频率

THE AMPUTVDE ENVELOPE, TRANSIENT PHASE AND FREQUENCY OF THE SEISMIC TRACE

本文讨论了求取地震记录道的振幅包络、瞬时相位、瞬时频率等动力学信息的计算方法及其具体实现,给出了CYBER 1724机应用程序中计算时所使用的褶积因子。

This paper deals with the computational method from which the dynamic information of the amplitude envelop, transient phase and frequency of seismic trace are extracted. Its implementation is discussed as well. Moreover the convolution factors being used in the"application programme"of the computer CYBER-1724 are also given.
