I have two questions about Tx lines
1. Can we think of the Tx line in terms of just LC ladder. If yes, why can't this be thought of as a LC filter. In that case, the tx line would be a low pass filter. Increasing C would make the cut off freq even lower.
2. If I don't terminate at the load and have a high impedance load, then I would see 2x the incident voltage at the load. If there is undershoot/overshoot, can I use a stub to eliminate this?
I am aware of the stub matching, smith chart etc. I am unable to apply this technique to PC board.
What I did in class was rotate towards generator/load and place the stub at a point along the tx line. How do I apply that here!?
