I need a detailed Analysis on this circuit

[patuno]

Good day dear friends, am a new guy who just picked interest in electronics, I was given a little project to execute and I found someone who helped me with the circuit, and I simulated it on Proteus and it worked fine but the problem is that the person has little theoretical knowledge about electronics, and I would have to defend the project both practically and theoretically. So please as many as those that can help me with a detailed stage by stage analysis of this circuit which is attached to this message, including the voltage, current at every stage and the essence of each component at each stage. I wouldn't mind if your explanation would be in an ms word format and dont forget to include your name if you wish, so you can be properly referenced. Thank you so much in anticipation

seriously !! ??

you don't even show power rails for the chips in the lower left

you said that you have simulated it, you should also be able to in the simulation measure voltages at various places

sooooooooooo..............
how about YOU describe each stage and people here can tell you if you are on the right path or not

I'm with Dave.
If you intend to learn something,put some effort into it.

Here is something for you to start from:
Can you resolve the question marks in the pic below?

While you are at it . . . . also explain the relevance of 80----> 120 <--- 160 ~ 's in the feed back loop.

Sounds like someone wants us to write a working paper on some form of college/uni homework!

I've never seen a request so un-subtley put!

What!? You have never received an e-mail from a Prince in Nigeria offering to share his fortune with you? You only have to send him a good-faith deposit to secure the balance of $_________ (fill in the blank) yada, yada, yada... I am not sure what the scam here involves, but I am pretty sure no one here wants to become entangled in it. Yes, it could be a student wanting us to do their homework. So what? We don't do that here.
