direct port
7.By using the measure and research of the emulating two-port network parameters of using direct-current analysis and figure value output function of sinusoidal steady state circuit in circuit emulating software PSPICE8.0, the measure and research have solved the problem of the measuring purely resistive network of simple and odd one in traditional experimient, and also brought about the analysis of alternating current and direct-current for two-port network of any one complex and measure and research of Y、N、Z、T、H and so on parameters, and this opens up one new path for many traditional experimient of not easy to fulfil and for the complex circuit.
