<DIV><FONT color=#000000 size=2>I have problems with my saw to triangle
converter. On the positive peak I noticed some sort of clipping, but it's more
like nonlinearity of the diodes. I've tryied several designs, but they are all
the same. Same clipping at the top, since the negative peak is ok and is sharp
as a needle :). Is that normal or what? This is especially noticeable at lower
frequencies. Has anyone experianced and solved similar problem? I've already
tryed several diodes (Ge, Si) and even BE diode in NPN transistor. No change :(.
I think the problem is not in design (since it work ok in silmulator), it has to
be something else. Note that I've also tryed several input amplitudes, but again
no change in quality. So I hope someone has solution, because this clipping
really bothers me a lot. The design is at:</FONT></DIV>

<DIV><FONT size=2></FONT><FONT color=#000000 size=2>Even tryed Korg MS20 saw to
tri, and Formant saw to tri and they all do the same clipping. Maybe it should
be that way? Btw. I am using soundcard as a scope, so maybe there lies a problem
(but sawtooth has no clipping at all).</FONT></DIV>
