ISOL-8: Cross Contamination Explained.

They tell us .....

The problem of noise cross contamination through power supply is often overlooked. Reducing its effect can result in significant performance gains for any system.

The key point is to understand is that each system component is not blameless and generates significant mains noise itself. In terms of power supply, it is also usually in close proximity to other components in the system, compounding the problem.

If you have system that contains a single component, one filter will protect it from mains borne noise
