Printed Circuit Board Power Bus Decoupling Questions

7. How do I estimate the amount of noise on the power bus of a printed circuit board that hasn't been built yet?

The answer to this question depends on what you already know about the board and its components. Generally the more you know, the more accurate the estimate. Here are some references that can get you started.
