How to eliminate noise interference from GND wire?

The reason why GND wire can cause magnetic interference is there is GND wire resistance. There will be voltage at the GND wire when the current flows. Under the drive of this voltage, the GND loop-circuit current is generated, causing GND wire loop-circuit interference. When the two circuits share a common GND wire, the common-impedance coupling will be generated.
Solution
Cut down the GND loop circuit, increases the GND loop circuit resistance, use balance circuit. To solve the common-impedance coupling, the user can reduce the resistance of the common part, or apply parallel single point grounding to eliminate common resistance completely.
