Transmission Parameters of Single Vertical Resistor

Click For Summary
SUMMARY

The discussion focuses on calculating transmission parameters for a two-port system consisting of a single vertical resistor. The user questions the feasibility of determining ABCD parameters when the output port is shorted, resulting in infinite currents I1 and I2. The conversation highlights the relationship between the T network and the single resistor's transmission parameters, emphasizing the need for transformation formulas to derive accurate results. The user seeks clarification on discrepancies between calculated and theoretical matrices.

Hello every body...

Consider two port system having a resistor (can it be called two port system?)...

____---->I1________________I2_<----_________

V1 / Resistor V2

_________________________________________

Is it possible to calculate Transmission parameters for this one?...
When we short the output port, the equivalent resistance becomes zero...
and I think, the currents I1 and I2 become infinite
The parameter D=(I1/I2) when V2=0 gives rise D=∞/∞
Then how can we calculate ABCD parameters for this...?
Thanks for any replies...

Now if I suppose the transmission parameters matrix for T network is [T] and for this single resistor is [v]...
I can calculate the overall T parameters for cascaded network of above two networks...and I suppose the matrix is [O]...
Then from theory, [O]=[V][T]
Then this [O] will not be equal to the directly calculated [O] matrix...
Why?

Thanks in advance for any replies...

1. Compute the z parameters.
2. Use the available transformation formulas to convert z_ij into a_ij.
3. To convince yourself of the validity of this approach you should concatenate two resistors R1 and R2 and show that the resulting ABCD parameters of the R1 and R2.
