Hi, Many thanks to you all for such a wonderful FOSS package. I have been experimenting with QUCS and would like to see how it performs if lumped element transfer functions are replaced by their Laplace transformed or s-domain equivalents. However I have not been able to find any reference to a way to do this in QUCS other than this in the forum: http://sourceforge.net/p/qucs/discussion/311050/thread/b85e50d9/#a1e7/e5fc which suggests that the Laplace operator, s, is allowed in the RF EDD. When I create a simple circuit using this RF EDD device, it does not seem to offer me the option to enter a Laplace expression such as: (s*10+)/s*11+1) It does offer me the option to enter information in terms of S, representing Scattering parameters but that is not what I am trying to do. I cannot find any information about this from the documentation page, in particular: http://qucs.sourceforge.net/docs/equations.pdf or http://qucs.sourceforge.net/docs/workbook.pdf Any help on this would be very much appreciated.
