I doubt there will be a useful visible difference. > > If anyone knows of anything like this, I'd be keen to hear. Dare I suggest - spreadsheet. Make columns with sin(2 * pi * frequency * t) Add them, graph them.... As you can see the 'best' answer will depend a lot on what your skills/interests are... some possible search terms: scilab matplotlib gnu octave _______________________________________________ Linux-users mailing list [email protected] http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
