    Greetings and welcome to the AAC forums!

    The Homework Help section asks that you post up the work you have done so we can see it and find where you went wrong, or suggest better approaches. We will not do all your work for you.

    If you are in doubt about how to structure your post and what to include please read this thread: http://forum.allaboutcircuits.com/showthread.php?t=3002

    Thank you.
