Wow! Nice! Thank you very much, I will dive into the report. As for non-linearity, I think I already read your comment when I was preparing my DSP assignment at uni. To detect and deal with non-linearity I have decide to stick with this swept sine method <http://ant-novak.com/swept-sine.php> though, as it is more intuitive for me. It also makes it pretty easy to identify Polynomial Hammerstein model filters.
