I m on my final year of electronics engineering ( undergraduate) focusing on mix-signal design. And, I have to do a design project: (2 sem long). I was just woundering if anyone has any idea about what topic /issue would be good  in my specific area.
Thanks in advance.

I guess electronics and electrical engineering are the same !!! Doesn't your college provide the projects? I did one in my undergrad and it is all group projetcs. So, u should have the same and you could do anything but choose something better one!!! In my time, projects like "determining Fault" for Power measure, Something about Direc Tv, there was other project for GPS navigation for northgroupman for communications, Micro Mouse for computer and so on !!!
