I am writing this review for ECE 163DA instead of 164D, but the materials are identical anyways. During the first lecture, the professor warned people that if we have not taken ECE 115A, we would have to make extra effort for this class - this was not true, and some people still ended up doing well in this class. Even though this class was quite time consuming because of all the brute-forcing I had to do to make things work, I also found it rewarding. The whole class consisted of three projects (we ended up doing two), and step-by-step design process could be found in the course reader, so it's really important to get one. During the presentations, the professor made harsh comments such as students not speaking loud enough, not looking at the audiences, etc., which may have sounded mean at first, but he meant well, and he ended up grading the assignments nicely. Overall, I would recommend taking this class with Professor Chang.
