SUMMARY

The correct method for analyzing two-port networks involves using the normal complex number Zg rather than its conjugate. In the context of impedance matching, the image impedances of the network should reflect the actual impedances of the source Zs and load Zl. The discussion clarifies that the use of Zg in its normal form is essential for accurate calculations in two-port network analysis.

Homework Statement


If we have a two-port network, a source with impedance Zs and a load with impedance Zl, I think that the conjugate of Zg and Zl (normal, not conjugated) should be equal to the image impedances of the network.

The problem is that I was told that instead of the conjugate of Zg the normal complex number Zg should be used.

Which is the correct method?

I think that the conjugate of Zg should be used since the image impedances are also conjugates of the source and load impedances.
