Hello all, As a remark on your observation Andy I would like to say in my defence that I simplified and reduced the problem/information simply to avoid wasting anyones time with details and (in my opinion) irrelevant side effects. That the two load resistors are in fact a representation of two complete sub-systems is in my opinion not relevant to the question I was asking. But maybe that was a mistake.
Nevertheless I got very very great and useful feedback from this list with the information I provided. I decided that I need C1 to eliminate any DC component from the input signal and the hits for using a transformer has let me to understand my error in thinking. It was never my intention to waste anyone time by holding back information but it was my intention not to waste anyone's time by reducing the number of details ;-) What I should do in the future is be more clear about the kind of information I would like to get from this list. a. complete design b. detailed design solution c. tutorial on electronics d. coffee-machine feedback I was looking for the last one, just some feedback from other professionals to get me on track to a solution. And that's what I got, in our situation the solution is to use a transformer, thanks everyone! Cheers, Robert. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
