有源电路和无源电路术语的讨论

Discussion on the Terms of Active Circuits and Passive Circuits

本文讨论了理想电路、实际电路中有源电路和无源电路术语的精确含义和受控源的概念,指出理想电路中有源电路和无源电路术语容易引起歧义;举例说明含有有源元件的理想电路既可以是有源电路,也可以是无源电路。笔者提出了对理想电路应使用理想有源电路和理想无源电路术语,对实际电路应使用实际有源电路和实际无源电路术语的观点。

The precise meaning of the terms such as active circuits and passive circuits in the fields of actual cir- cuits and ideal circuits, the concepts of the controlled sources are discussed in this paper in detail . It is pointed out that the terms such as active circuits and passive circuits in the field of ideal circuits easily lead to ambiguity . It is illustrated that the ideal circuits containing the active elements may be either active or passive. They are suggested that the terms such as ideal active circuits and ideal passive circuits are suitable for the ideal circuits, and the terms such as actual active circuits and actual passive circuits are suitable for the actual circuits.
