Assumed you meant (A^2/B^2) , (A*A/B*B) is (could be, depending on interpreter) different.

Why is this? If we are wanting to see only a ratio of the theta to beta, then squaring each would only give you the same ratio, so what's the point of this seemingly-extra step?   Second question: Is the "Averager" which follows truly an averaging module, or has it been so-labeled because it simply samples the incoming data every 256 (if set to that number, for example) times?
