Two-port network is an important component of the teaching of circuit theory. How to allow students to learn and flexible application of the network parameters has been teaching circuit theory to explore the issue. Based on the conventional ]umped parameter circuit model, parallel-parallel, parallel-series, series-parallel and series- series connection are discussed. Then all the parameters are transformed to Y parameter in order to analyze voltage gain, output power and efficiency conveniently. Teaching results show these methods can help students to enhance their engineering concept, and arouse students＇ learning interest.
