Transmission Parameters of Single Vertical Resistor

AI Thread Summary
The discussion revolves around calculating transmission parameters for a two-port system consisting of a single vertical resistor. It questions whether the system can be classified as a two-port and explores the implications of shorting the output port, which leads to infinite currents I1 and I2, complicating the calculation of the ABCD parameters. The user proposes a method to derive overall transmission parameters for a cascaded network of a resistor and a T-network, but expresses confusion over discrepancies between directly calculated and matrix-derived parameters. The conversation suggests using z parameters and transformation formulas to clarify the calculations. The need for practical verification by concatenating resistors is also highlighted to validate the approach.

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.
