I have constructed the following circuit in HSPICE,and it gives me the following waveform

I know that we have the first wave hit node 3 then it goes back and again to node 3.

But how we construct the impedance to time domain plot from this voltage to time plot?

Thanks. enter image description here

  • I know that we have the first wave hit node 3 then it goes back and again to node 3 - that isn't true if the t-line is 50 ohm; there won't be a reflection at the source. But how we construct the impedance to time domain plot from this voltage to time plot? - I'm unsure what you are wanting to do here. – Andy aka Mar 11 '21 at 08:38
  • Hello Andy, i Want to know how using TDR (voltage to time plot)we find the source of the INSERTION loss problem if it arives.(exact location of problemtaic spot) – ron398 Mar 11 '21 at 08:48

    Maybe this will help. Maybe this will help. I'm offering these QAs because I'm struggling to understand what it is you really want to know @ron – Andy aka Mar 11 '21 at 08:51
  • Hello Andy ,Th ecapacitor causes this small dip, i cant see why? could you plaese help me with the reflection logic here? Thanks. – rocko445 Mar 13 '21 at 18:59
