Hi Everyone

At the webpage, http://www.geocities.com/anderson_eee/accuratebit.gif

How do we now how much accuray of bit is needed at each node?
For example, at the amplifier with 8 bit, why 5 bit acccuracy is needed? May I know how to get that?
But then, may I know what is the number '8' written in the amplifier? Is it the gain? If it is the gain, then how do we know gain of 8 is needed in this example?
Thank you for your help in advance.

regards and thanks
