翻译如下 1.We remember signal f (t) of the corresponding Laplace function f (s),its Laplace transform (inverse).Laplace AAAAA,inverter change for bsde BBBB,criterion for bsde can write to Laplace transform for CCCCC: Corresponding to the two formulas,can for most signal Laplace domain with a - domain any change. Simply speaking,asked for a signal is to give it the Laplace function by a DDDD attenuation factor (which can make the signal of its convergence),again on points. 2.And know F (s),the corresponding F (t) is also very easy to get. 3.The analysis method is also called S domain analysis or after the frequency domain analysis.
