- I have a question about this Smith Chart copyright discussion...
-
- How is it that you can copyright what is basically the mere plot of a
- mathemetical function!? (z=(1+k)/(1-k))
-
- I mean... if I really didn't have better things to do with my time, I could
- have my HP-48 plot a Smith chart, right? Would that be copyright infringement?
-
- I realize that if you have _the_ Smith chart produced by ??? Electric, you
- can't copy it -- just like a book. But if you regenerate the plot from the
- mathematical model? This seems odd to me... if so, pretty soon people
- will want to copyright things like the Mandelbrot set, etc.!
-
- Very strange...
