也谈离散系统状态方程时域解中一个易忽略的问题

Discussion about “A Overlooked Problem on Time Domain Solution of State Equation of Discrete Systems” As Well

本文利用离散卷和概念 ,从数不角度讨论了离散系统状态方程的时域解问题 ,同时也证明了本刊 1999年 3月刊登的“离散系统状态方程时域解中一个易忽略的问题”一文的正确性 。

Making use of the discrete convolution,this paper discusses a problem on time domain solution of state equations of discrete systems.At the same time,it demonstrates the correctness of the paper “An Overlooked Problem on Time Domain Solution of State Equation of Discrete Systems”,which was published in this magazine last year.It also can be taken as supplementary method of this kind of problems.
