transmission line demo 2

[Doug Stewart]

For those that are interested My demo can be downloaded from

http://dougs.homeip.net/scicos/trans4.cos

The demo as it is, shows the reflections when the  load is high 
impedance (open circuit) with a line resistance  close to zero.

You can then change the load resistance to 1 ohm   approximately  Zo and 
show that there are no reflections.

You can then change the load resistance to 0 ohms   and show that the 
reflections are now inverted.


 You can go to "context" and change any of the line values  and run the 
demo again.

And you can put a complex load on it to demonstrate impedance matching 
for lossy lines.

If any body can see how to improve on this I am ready and willing to 
listen :-)
My goal was to demonstrate (in a physical way?)  what the formulas are 
already telling them.
Yes I know you could use a rope tied between two trees :-)
