Hello,
I have designed a board that consists of an audio circuit and a fan
controller circuit.
When the fan is running it induces audible noise in the audio circuit, I
can hear in the speakers the fan spinning.
Can anyone please address the following questions:
1. How's the fan audible noise getting into the audio?
2. How can I get rid of this interference?
Thanks,
Brahim
