Some Discussions on Sampling Control System

讨论采样定理的实验验证问題,分析采样时间对系统性能的影响,并提出用留数法进行Z变换时应注意的问題。

The problem of experimental verification about sampling theorem is discussed, the influence of the finite duration of sampled signals on the performance of system is analysed, and a problem that should be noticed while using residue theorem to find Z—transform is posed.
