1. The problem statement, all variables and given/known data Can someone help me solving this problem ? A lossless coaxial cable is used in a data network. it has an er =3 (relative permittivity) It is driven by a pulse source with internal impedance of 10 ohm, 1 V amplitude, square wave with duration of both positive and negative pulse 50 ns, with negligible rise and fall-time. Sketch the voltage at the end of the line as function of time for 300 ns 2. Relevant equations 3. The attempt at a solution The Zc = 50 ohms from caluclutation. The one way time delay due to the cable length is 58 ns. At start a voltage of 5/6V positive will propagte to the end it will be there after 58 ns and it will last till 108 ns. after that the negative pulse of -5/6 V will reach the end on 108 ns and will last till 158 ns. I have no idea how it will be with reflections?
