Lossless Line
For a lossless line, R and G are both zero, so the equation for characteristic impedance reduces to:
The imaginary term j has also canceled out, making Z0 a real expression, and so is purely resistive.

Famous quotes containing the word line:
“A route differs from a road not only because it is solely intended for vehicles, but also because it is merely a line that connects one point with another. A route has no meaning in itself; its meaning derives entirely from the two points that it connects. A road is a tribute to space. Every stretch of road has meaning in itself and invites us to stop. A route is the triumphant devaluation of space, which thanks to it has been reduced to a mere obstacle to human movement and a waste of time.”
—Milan Kundera (b. 1929)
