Hello list,
A while ago I posted the code of my pole-zero analysis tool in SC.
I've been
working hard on an improved version of this. I fixed some bugs and
added
some new features. I'm sure I forgot some things and possibly
the documentation could be a little better, but anyway, here it is!
I hope
some of you will enjoy playing with it and most important, find it
useful in
some way. Any comments are more than welcome.
New features and improvements:
- Dragging of multiple pole-zero pairs around the unit circle with
the mouse
is possible (I'm pretty proud on this, I have to say)
- Automatic detection of identical poles and zeros (pole-zero
cancellation)
- Better handling of and response to user input
- Sound examples (Unfortunately only works for 2 or 1 pole-zero
filters for
now. I have tried to cascade multiple SOS filters to obtain higher
order
filters, but did not succeed (yet).)
gr.
Michael
