An electrical and electronical engineering question

[icarus88]

Friends, I didn't know where to post this thread. An electrical and electronics engineering question: How can I prevent the components that draw instantaneous current and decoupling capacitors in systems that use digital microprocessors, which cause background noise, from using the grounding line brutally? Is there any software that can do this?




is it impossible?

There's a lot that can be inferred and misinterpreted from your post. What specifically are you trying to accomplish?

Breaking the CPU and GPU micro ground loop

 

[silky smoove]

Assuming the CPU and GPU are in the same machine, why is there a ground loop in the first place? Do they have separate power supplies that you're sending to ground in a way that creates a loop?

No they don't have separate powers

 

[silky smoove]

No they don't have separate powers

Then where is the ground loop occurring?

In decoupling capacitors

 

[icarus88]

Most of the GPU noise is being directly injected into the ground plane.

Software? No.

Under those terms, yes, impossible.

Just reduce the frequency of running CPU and GPU, that makes them slower and reduces "background noise" because the changes in the capacitors will be slower, too. If you cut the power, all "background noise" is eliminated, but nothing works anymore.
==> best leave the problem of reducing your "background noise" to the engeneers designing the systems.
If a system is shielded correctly and the power supply well designed, there should not be too much effect to the outside of the system.
I think, your question is in totally the wrong forum....

I should write in the audio science forum but I'm not a member. I'm not sure why I'm so obsessed with these topics

I'm actually doing intellectual fantasy. ))

Assuming you are trying to fix the background noise in your studio?

 

[icarus88]

the fantasy part is, without using daw software, completely zero background noise, no EMI, no RFI, no ground loop.

 

[lowfreqgeek]

Zero noise isn't theoretically possible, let alone practically possible.

A resistor is a noise generator, regardless of whether it's connected to anything or not. And on and on it goes.

Could you maybe rephrase this in meaningful language?

I have no idea what "using the ground plane brutally" is even supposed to mean.

Humanity, which sent a rocket to Mars, will certainly achieve this one day.

Physics says no, although thermal noise is dependent on absolute temperature (in Kelvin), so the only way to approach theoretical 0 is to operate at 0K. But there are other fundamental noise sources that have their own peculiarities.

hmm, I forgot about the thermal noise issue.

I ordered a USB 2.0 isolator, which was discussed and tested on the audio science forum.


their industrial production is new.
their chips are used in MR devices and nuclear facilities.
