medium📝 Formula Result Q13 of 15
Step-by-Step Solution
Solution:
Step 1: Understand guard trace effect on signal
A grounded guard trace reduces noise coupling from nearby signals, improving signal quality.Step 2: Analyze options
Signal quality will improve by reducing noise coupling correctly states that signal quality improves by reducing noise. Other options are incorrect or unrelated.Final Answer:
Signal quality will improve by reducing noise coupling -> Option CQuick Check:
Guard trace effect = Noise reduction [OK]
Quick Trick: Guard traces reduce noise, improving signal quality [OK]
Common Mistakes:
MISTAKES- Thinking guard traces increase noise
- Assuming guard traces speed up signals
- Believing guard traces only affect power lines
