after the course ends there's a retreat . i'm definetly study
someplacve good . and surely they have good places in here .

about what your saying about the iir filters :
you should try starting at
eg3.com
or there's some dsp site of rice university
or any big university with dsp degree
have you tried those ?
and also have you tried lookingon groups on wavelets - i remeber i
have seen some wavelet group.
and maybe you can go to some big electronics journal like :
www.ednmag.com
www.edtn.com
and ask them for a little help how to find a person like this .
try .
in two weeks if you can find - i'll be out of the course and
i 'll try t help .
