A PCB designer needs to reduce electromagnetic interference (EMI) in a mixed-signal board. Which combined approach is best?

hard📝 Scenario Q8 of 15

PCB Design - Design Review and Testing

AUse ground planes, separate analog and digital sections, and route signals carefully

BIncrease trace lengths and add more vias

CPlace all components close together without ground planes

DUse thin traces and avoid decoupling capacitors

Step-by-Step Solution

Solution:

Step 1: Identify EMI reduction techniques
Ground planes and physical separation reduce noise coupling.
Step 2: Combine layout strategies
Careful routing and separating analog/digital sections minimize EMI.
Final Answer:
Use ground planes, separate analog and digital sections, and route signals carefully -> Option A
Quick Check:
EMI reduction = Ground planes + separation + routing [OK]

Quick Trick: Combine ground planes and separation to reduce EMI [OK]
