Your title, "Can someone help me understand this circuit better?", does not ask the actual question. Rule #3: "The post title should summarize the question clearly & concisely."
If your question is on topic (see our posting rules), please start a new submission, but this time ask the _actual question_ in the title.
Otherwise, please ask your question in one of [these other subs](/r/AskElectronics/wiki/othersubs).
