Lossless transmission line with characteristic impedance Z0 and frequency F The lossless transmission line TLine3 is a two Port. Both port branches consist of a resistor with value of the characteristic impedance Z0 and a controlled voltage source that takes into consideration the transmission delay. For further details see Branin';s article below. Resistance R'; and conductance C'; per meter are assumed to be zero. The characteristic impedance Z0 can be derived from inductance and capacitance per length (L'; resp. C';), i. e. Z0 = sqrt(L';/C';). The length of the line is equal to a quarter of the wavelength corresponding to the frequency F, i. e. the transmission delay is the quotient of 4 and F. In this case, the characteristic impedance is called natural impedance.
