A basic time domain reflectometry (TDR) system is used
with an oscilloscope to display the waveform of the input end of a
line in a non return to zero digital system
A 1000m cable is terminated with a short circuit at the far end.
The first reflected wave appears 9.43 micro seconds, after the
incident waveform. The actual velocity in the cable divided by the
speed of light is?
A. 0.35
B. 0.71
C. 1.0
D 1.41
