摘要
在采样系统的分析中,系统的脉冲 Z 传函 G(Z)或者系统输出的 Z 变换Y(Z)的求取是十分重要的工作。本文提出一种“星”运算法,并在此基础上推导证明了适用于采样系统变形的 Mason 公式,利用此公式,可以方便地求取某些采样系统的 Y(Z)或 GB(Z)。
In the analyse of a dispersed system,it is important to get the G(z) or Y(z) of the system.In this paper a method named“star” has been introduced and the changed Mason Formula has been proved too.It is quite convenient to get Y(z) or G(z) of a dispersed system by using the changed Mason Formula.
