Here,There is a pulse going through a transmission line.There is a phenomena where if we put a pulse through a transmission line then after it reaches the IC we can have ringing instead of good pulse. In LTSPICE simulation connector is represented as pulse voltage source of 6V with resistor in series. Transmission line is represented as RLCG .The load is 2 Ohm because 6V/3A=2Ohm. As you can see i could not get oscillations from this transmission line. I was expecting to see a picture as shown in the end, instead I got in the plot saw shapes which very stable response. Where did I go wrong with this simulation? Thanks.
