Homework Statement


Circuit schematic of a two-port network with ports labelled 1 and 2. A series resistor of 8 Ω runs along the top between the input and output, and a shunt resistor of 6 Ω connects the top and bottom wires at the junction. Text on the left reads: Find the z-parameters of the two-port network given.


Homework Equations




3. The Attempt at a Solution

Z11 8 + 6
Z12 6
Z21 6
Z22 6

V1 = Z11 I1 + Z12 I2
V2 = Z21 I1 + Z22 I2
 
Was there a question to go with this?

We won't just confirm raw answers; you need to how your work.
 
I just follow course notes. The question is exactly as above.
 
The example above is slightly different than taught ones hence the question.
 
T-network circuit with R1 and R2 in series on the top line, R3 as a shunt branch down to the bottom line, and a table listing z11 = R1 + R3, z12 = R3, z21 = R3, z22 = R2 + R3.

This is what I came across and that is where my attempt comes from. cheers. Am I on the right track?
 
Once again, we don't confirm guesses.

Rather than trying to extrapolate a guess from a given example I'd suggest using the definitions of the individual z-parameters. Your text or course notes should define them in terms of port currents and voltages. Barring that, Wikipedia does a reasonable job showing their definitions. With them you can find the parameters for a 2-port network and be confident in the results.

You probably won't have handy examples to work from on an exam ;)
