Description
Lossless transmission line with characteristic impedance Z0 and transmission delay TD The lossless transmission line TLine1 is a two Port. Both port branches consist of a resistor with characteristic impedance Z0 and a controlled voltage source that takes into consideration the transmission delay TD. For further details see Branin's article below. The model parameters can be derived from inductance and capacitance per length (L' resp. C'), i. e. Z0 = sqrt(L'/C') and TD = sqrt(L'*C')*length_of_line. Resistance R' and conductance C' per meter are assumed to be zero.
