When asking academic questions, you will learn the material a lot more if you do as much of the problem yourself as possible. Also it is officially the policy on EE to only give guidance not solutions (although it happens sometimes anyway).

So, what do you think the answer is or how do you think you should approach it?
Where are you stuck? etc. Please include this type of information when posting academic questions and then we will gladly fill in the missing details.
