I had the cool experience of taking that class from Prof. Horowitz himself. Not only was the class great, but there were lots of stories around the department of him solving electronics problems for other professors’ experiments (my favorite was probably one where a team flew him out to CERN in Switzerland, expecting the problem to take a few days to solve. On the way in from the airport, Horowitz asked them to stop at the lab and show him what was going on. They said there was plenty of time and they would get started the next morning. Horowitz insisted, and they finally relented. They stopped at the lab and showed him the experimental setup and described what wasn’t working. He grabbed a wire, soldered it in, problem was fixed, and he enjoyed a couple of days of vacation in Switzerland.)
