I'll do this by showing you how to improve the grounding and reduce the crosstalk. These rules apply to both analog , digital and RF electronics. I'll also share some rules of thumb for PCB parasitics that you can use in electronics simulations. I'll prove my points with actual measurements on dedicated test PCBs. In this fourth part I'm showing the advantages of ground on all layers, and how to get rid of the potential disadvantages.
