TLine2

Lossless transmission line with characteristic impedance, frequency, and normalized length

Modelica Standard Library

	Description
	The TLine2 component models a lossless transmission line with characteristic $Z_{0}$ , frequency $f$ , and normalized length $NL$ . The delay is given by $T_{D} = \frac{NL}{f}$ .

	Equations
	$e_{r} = 2 delay (v_{1}, T_{D}) - delay (e_{s}, T_{D})$ $e_{s} = 2 delay (v_{2}, T_{D}) - delay (e_{r}, T_{D})$ $T_{D} = \frac{NL}{f}$ $i_{1} = i_{p1} = - i_{n1} = \frac{v_{1} - e_{s}}{Z_{0}}$ $i_{2} = i_{p2} = - i_{2} = \frac{v_{2} - e_{r}}{Z_{0}}$ $v_{1} = v_{p1} - v_{n1}$ $v_{2} = v_{p2} - v_{n2}$
