I'm trying to use qucs in my school for simulating voltage pulses traveling in transmission lines.
Here (http://lnx.rete3apuglia.it/qucs/tline_prj.tar.gz ) are some example I'm working on.
Bun only few of them work.
Can somebody explain why?
thank you in advance
The problem is that you are doing a transient simulation on a component (transmission line) which has not been defined for this type of simulation.
If you have a look at the following page, you would see that some components are not valid for all types of simulations.
