Example Traces
These traces were produced by the Time Domain Reflectometer made from common lab equipment connected to approximately 100 feet of 50 ohm coaxial cable. The propagation velocity of this cable is approximately 66% of the speed of light in a vacuum.

Famous quotes containing the word traces:
“True Civilization does not lie in gas, nor in steam, nor in turn-tables. It lies in the reduction of the traces of original sin.”
—Charles Baudelaire (1821–1867)
“The new man is born too old to tolerate the new world. The present conditions of life have not yet erased the traces of the past. We run too fast, but we still do not move enough.... He looks but he does not contemplate, he sees but he does not think. He runs away from time, which is made of thought, and yet all he can feel is his own time, the present.”
—Eugenio Montale (1896–1981)
