Comment: lecture notes are so good that you don't need the textbook (as long as you also go to lecture and recitation). doesn't assume much prerequisit knowledge, but math 110 (and maybe math104) would help.
EL ENG 222 (Spring 2011)
Comment: Assignments can sometimes have a lot of tedious algebra. This was remedied after the midterm evaluations though. Prof. Tomlin is very well prepared and offers a lot of structure. Prof. Sastry's textbook is very thorough and sometimes quite dense so attending lectures is very important for understanding the material. If you have a strong background in differential geometry, topology, and analysis lecture might not be as important.
