This question is closed because the diagrams are unreadable. You should have been able to see that for yourself. Each circuit should probably be a separate image, and any text between should be normal text in the question. Text in images doesn't work for indexing and searching. While you're at it, make sure each component has a unique designator. Ping me when you've fixed the question so that I can re-open it.

Ok it is ready for reopening

Hmm. It's still pretty hard to read. What's that thing in the top middle of the schematic, for example? Also, the equations in your text are unreadable. We have MathJax here for that. I'll reopen it this one time, but in the future this won't be good enough. You wouldn't hand in homework this illegible. We deserve no less, especially considering your professors are paid to read your homework. We are all volunteers here.
