Z逆变换定理的建立及应用研究

A Study on the Establishment of Z Inverse Transformation Theorem and its Using

本文对Ｚ逆变换中的留数法合理地给出假设条件，并用复变函数中的罗伦级数、留数理论给出了严谨、简捷的证明．

The assumptive conditions are given reasonably about the residue method of Z inverse Transformation, and a close forthright prove is given by the theory of Laurent series and residues in complex function.
