Transmission Parameters of Single Vertical Resistor

  1. Dec 21, 2011 #1
    Hello every body..........

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

    + | +
    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.......

    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.
