Circuit theorem analysis in analog circuits and its application

Based on the nonlinear analog electronic basic amplifying circuit,the application of circuit theorem is worked out(Kirchhoff's law,superposition theorem,Thevenin's theorem)analyses and solution of analog circuit such as the ideal operational amplifier circuit and amplifying circuit.This method can be used to reduce the difficulty of circuit analysis.And it can also simplify the process of solving problems,shorten the solving time and reduce the analysis of error.Meanwhile,it promotes the students' ability to use the circuit theorem analysis,and to solve practical problems.
