some courses are not in the berkeley webcast site, like eecs 242. i guess it has been stored there, and then been removed.
i would like to know where i can find such backup.
You can search for EE142. Its same as E242 (RFIC). EE142 is for undergrad and EE242(grad). Same course notes and same class,but former will not do a project,latter will do a project for credits.
I think u can got Dr. Ali Niknejad website to download lecture notes and project stuff.
