Hello electrical engineers and hobbyists of PhysicsForums! This is my first post (I think... I might have posted before) and I am a junior-year EEE student at a local University. I have some free time this summer and want to study/review some concepts to be fresh when I need them for my upcoming classes next semester. Here are the classes I am taking: 1) Signals and Systems 2) Introduction to Microprocessors 3) Electronics 1 (solid-state devices) I was thinking of reviewing series and sequences, and maybe some differential equations for numbers 1 and 3, and I am pretty good with C++ which hopefully will help with #2. I do not have the syllabi for these classes yet but I can get them for 1 and 2 to see what I might run into there. I'm a bit nervous about Electronics 1 because I have heard it is very challenging and not very intuitive so any prep I can do now will help. Any suggestions are welcome but please do not post if you are going to be rude or sarcastic (unless it's really, really, really funny.) Thanks!
