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元件组成的本电路模块，其本电路的传递函阶。

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.

可以用不的有源器件本电路中的零极子对，得到电流传输器型（CCⅡ型）和通用运算放大器型（OPA型）电路。
