Turn The Screws!

Open your eyes, look in front, look at the back, look at any angle and you will see something that is an engineer's creation.

Engineers have been making things possible that others could only imagine. It perfectly makes sense to have a common place for engineers from around the world where they can share ideas, innovate, & help each other. Engineers are eternal, with the younger at 62 & the youngest at 17, the CEan gang consists of working professionals, students, entrepreneurs, CEOs, professors, geeks & nerds.

Question Guard traces for critical signals in PCB? Does it really protect!
Why we need guard traces for critical signals like video or audio analog signals....

is it really plays good role in eliminating interference... or any other remedy is there?

Thumbs up Re: Guard traces for critical signals in PCB? Does it really protect!
Yes, Guard traces do help a lot in reducing adjacent channel interferences in analog signals. It depends on your interference level requirement. If it is very strict, you may surely need a guard trace. If not, just keeping the traces a few mms apart should suffice.
