Hallo!
I think maybe another good example would be an 'adaptive line enhancer' for something like automatic removal of mains noise from broadband signals, but its not needed, it's already nice as it is.
:) - yes, of course, there could (and maybe will) be much more ... Also the code of the LMS and NLMS is not really optimized, but maybe I'll do it when I need it ...
