nullator

1.The transformation function of a circuit composed of nullator-norator and RC component is of the second order.

摘要分析了由零极子对和RC元件组成基本路模块，其基本路函数为二阶。

2.Thus, replacing the nullator-norator by active elements, circuits of current-convey type (CC Ⅱ) as well as general-purpose operational amplifier type (OPA) are obtained.

可以用不有源器件取代基本路零极子对，得到流输器型（CCⅡ型）和通用运算放大器型（OPA型）路。
