This paper expounds first on the advantages of Time-Frequency Analysis (TFA) technique in fine de- scription of graded pattern of sedimentation.Then it specifies the optimization design of T-F filter with frequen- cy recursion based on the practicability of T-F filter principles and performs T-F analysis of seismic responses generated by a theoretical cycle model of tectonic geology built through forward simulation method.It finally of- fers an evaluation of practical application through interpretation and comparison of the simulated and the real cyclicity.
