Re: gEDA-user: Weird DRC error
Hello DJ, Sorry, almost but not quite. If I apply the patch the DRC error in the original file disappears, but if I move the small polygon to the larger one keeping 6 mill distance no DRC error reappears. (DRC distance is set to 10 mill). If I make the distance between the two 5 mill then I get a DRC warning. I have looked in the source code and in my opinion the following code adjustment is also needed (in addition to your patch below): In the function IsLineInPolygon() -- if (!(lp = LinePoly (Line, Line-Thickness + Bloat ))) ++ if (!(lp = LinePoly (Line, Line-Thickness + (2 * Bloat) ))) Sorry for the clumsy way of showing this. The 2 * is needed because in LinePoly it will be divided by two. If I do this then it almost works ;-) If I move the two polygons 10.01 mill apart no DRC error appears and if I move the two polygons 10.00 mill apart a DRC error does appear (?). Looking at the log window I see Rules are minspace 10.01 But I have set it to 10.00 mill. Where does the 0.01 mill come from? I will keep looking at it but if I'm barking up the wrong tree please let me know.

gEDA-user: pcb crash
I was trying to draw some track between U4 and U2, pcb crashed, this is what i
could get from gdb, pcb file attached.

It seems i forgot to attach pcb in previous email.

Re: gEDA-user: RMS Waveform of a signal

I'm not sure what definition you have in mind for regular. Sorry about, I'm so bad with english (you know) and try to make it simply (and in many times wrong). Regular as without strange distorsions, and expresable with a common ecuation, like a sine wave, for example. [...] Sincerily, I thought that this are more usual, but there are very few references on web and nothing in how to obtain in free world (at least, I can't find it). RMS is usually not defined as time-varying. Usually you'd just find sqrt(average_over_time(signal^2)) and for something which is not periodic (like say a digitally modulated carrier with random data), you just average over enough time to where if you did it again later you'd get about the same answer. That RMS() function in the paper just uses a shorter window. In other words what they do is compute: sqrt(low_pass_filter(signal(t)*signal(t)) My guess is that the lowpass filter they use for the measurement is just a moving average meaning the impulse response is a rectangular pulse with a width of say 1/10 or so of the width of the waveform display. I'm afraid that I don't have idea how they implement these RMS, and possibly you are true. Perhaps we need the voodoo, how says Armin. I can tell you that the method used in my last mail almost fits the graph that I want. Possibly is wrong in mathematical terms, and is most correct use the aproaching [1,2]U[3,4]U...[n-1,n] intervals and expand it by spline to all the time analysis. In other way, the solution gave by Holger in Ngspice list, fits the graph wanted. So in octave you'd just square the signal, use the filter() function, and then sqrt. The trick is something like octave usually doesn't work on non-uniformly sampled data like what you'd get out of a simulator. Can I ask you how to use the filter() function? I see its needs a three vectors... and I want to test your method. -Dan Best regards. Salud y Revolución. Lobo. -- Libertad es poder elegir en cualquier momento.
