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] 1arrow_forwardA 2 V signal is incident to the interface from a 75 Ohm region propagating to a 50 Ohm impedance region. What is the reflection coefficient?
