Many basic circuits in the Analog Electronics can be regarded as the two-port network with three terminals,and they need to be decoupled into the input and output loops when their circuit characteristics are analyzed.However,the transformation of the impedance parameters from the original to the decoupled circuits is difficult to understand.This paper derives the parame-ters transformation of the parallel-or series-connected impedance in the two-port network with three terminals,and employs this method to analyze three typical analog circuits in the textbook.The proposed method can simply the analysis of the analog cir-cuits.
