双稳信号的参数调节及恢复

Bi-stable Signal Recovery with Parameter Tuning

为了研究系统参数对于双稳信号以及信号恢复的影响,首先分析了信号的恢复机理,并通过对小参数和大参数信号进行数值仿真,研究了系统参数对于单阱和双阱跃迁共振的影响以及信号恢复过程中的参数调节规律;然后根据对系统内在机理的分析以及不同信号的恢复过程,定性定量分析了信号恢复中产生的失真脉冲;最后将上述研究应用于两类不同信号的恢复,并提出了各自的恢复方法和消除脉冲失真的建议。

This paper focused on influence of system parameters on the bi-stable signal and its recovery.Firstly,the mechanism of signal recovery was analyzed.The small-parameter and large-parameter signal were simulated to determine the system parameters＇ influence on single potential well and bi-stable transition resonance as well as the parameter tuning laws.Then,the causes of pulse distortion during signal recovery were discovered by analysis of the system mechanism and the recovery procedure of different signals.Some measures of avoiding waveform distortion were presented.The results show that the method proposed in this paper is workable.
