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:
“When I had mapped the pond ... I laid a rule on the map lengthwise, and then breadthwise, and found, to my surprise, that the line of greatest length intersected the line of greatest breadth exactly at the point of greatest depth.”
—Henry David Thoreau (1817–1862)
