Or you could say what specifically you want clarification on.  Do you not
understand what is meant by two poles?  By shifting 8 bits?  What settling
time is?  How 93% was arrived at?  What an iteration is?  Why 1100
iterations?  Why shifting by 8 bits is particularly trivial?  Why 2 x 8 bits
is a lot of random noise attenuations?  What is meant by random noise?

Do you see how it would be unreasonable to try to answer all these questions
in a single message, especially since you probably only want the answer to a
few of them?
