Re: Rotary encoder

Good evening,
My encoder causes snaps in the top speaker. At the oscilloscope, we can see a few millivolts of the square signal caused by the rotation at the entry of amplifier
I tried to move the ground wire, add a couple of capacitors to it. no résults.
That noise is a bit distressing. Some of you have they found a solution? Added ferrite, shieds cable or other?

So, is the solution here?
An optical encoder:
