A coaxial cable is 10 meters long, and is filled with lossless Teflon, having a relative permittivity of 2.1. There is a matched load at the end of the line (this means that there is no reflection at the end, so there is only a signal traveling in the + z direction). At the input of the line, a sawtooth waveform is applied, having a peak voltage of 1.0 [V] and a duration of 1.0 [ns] (the time from the beginning of the waveform until the end).

Question
A coaxial cable is 10 meters long, and is filled with lossless Teflon, having a relative
permittivity of 2.1. There is a matched load at the end of the line (this means that there is no
reflection at the end, so there is only a signal traveling in the + z direction). At the input of the
line, a sawtooth waveform is applied, having a peak voltage of 1.0 [V] and a duration of 1.0
[ns] (the time from the beginning of the waveform until the end). Make a plot (versus time) of
what an oscilloscope would read if it were connected to the line at various locations,
corresponding to the following values of z: 0.0 [m], 1.0 [m], 5 [m], 10 [m]. Plot out to 50 [ns]
