Strange Transmission lines behavior?

2009-02-09

  • Hello folk

    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

      Hi Davide,

      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.

      Cheers,

      Frans

       
    • Got it.
      Many thanks.
