Lecture note which deals with noise in cascade systems

help

Hi All

I am doing electronic design from a physics background. In the class, I am lack behind for 2 semester and last semester I failed my RF IC design. reason is because I dont have the basics but it is a compulsory course to pass.
I need to know if anyone has any good document about the calculation of noise figure for a system consists of few amplifier, few passive component, receriver or transciever. I need to learn how to calculate such question in order to pass exam. I will take the subject again next semester.
Any tutorial or lecture sites for this topic?

Then I need to know if anyone has document about the theory of function for a walkie talkie , how they work and how they diffrentiate incoming and outgoing signal for both walkie talkie without interfering.
I really need to know this.

please help me

thank you
jason

Re: help

What you are asking is a very broad topic.
