摘要
本文对线性离散动态系统的连续化问题进行了研究·应用文[1]研究结果,给出了非带限信号采样率应满足的条件,导出了其拉氏变换与Z变换间的反演公式,并对一些文献中的模糊与不确之处作了澄清。
In this paper, the continuum problem of linear discrete-time and dynamic systems has been investigated. Using the results shown in Ref [1], the conditing of selecting the sampling rate of nonband limited signals is given, and an inversion formula between its Laplace and Z transform is derived. Moreover, this paper also points out the anbiguity and incorrectness in some references and the correct results are presented.
