Re: [Qucs-help] Transient SImulation Problem

[Claudio G. <cla...@vi...>]

...good to see that it can be made to work :)

I didn't try to set the min step that high since the source frequency 
is 3 kHz, so I thought a time step much less than 0.3 ms was needed to 
capture all the transient appropriately.
Still, the transient simulator in Qucs is not that robust and needs 
some improvement...

Regards,
  Claudio
