Hi welcome to Justanswer.
My name is ***** ***** I'm one of the electrical experts on this site. This appears to be a section from a (mostly communication based) test, or possibly the whole thing.
I can help you out with a few but a lot is out of my areas of expertise. Perhaps there is an expert in another category that could offer more assistance.
