| Abstract: | Based on the two-port networks analysis method, the math model of interconnection of two-port net-works was derived. Comparing this model with that of feedback circuit, we found that the parallel, serial, serialparallel, parallel-serial interconnections of two-port networks are the same as the four basic configurations of feedback circuit in structure, function, math-model and signal transferring. Then, we analyzed transistor feedback amplifying circuit with the concepts and method of two-port networks. The result shows that the paper＇s conclu-sions are correct. |
