Hello I'm moving from a T3.6 to a T4.1. My MUXs have a lot of noise when reading analog signals now (from the 600MHz MCU?) I have a separate ground plane for the pots I'm reading. I want to re-introduce the ferrite 600 on my board that is missing from the T4.1.

I assume 600 is 600ohms at 100MHz? Are there any other tips for removing noise, my PCB has 100nF caps on the pots, which have helped previously. Thanks.
