Professor Villasenor is pretty much my favorite professor in the EE department. A couple downsides about him:

1. He goes way too fast in lecture, so you have to pay real close attention to him because zoning out for even one minute may result in you getting lost during the rest of the class period.
2. His exams aren't very easy.

Nevertheless, he's very effective in delivering the material, and I'd like to take him again for another course. His homework assignments aren't too bad if you go to lecture, and if you go to the TA's discussion sections, they're a piece of cake. The midterm for that class was kind of tricky, but not terribly difficult, but the final was very tricky. I felt like his midterm was more computational while the final was more conceptual.

The computer assignments aren't terribly bad except for the last one, which felt like a CS 32 project, but considering the fact that this course is only offered once a year (at least during the year I took it), I highly recommend 114 with Villasenor.
