Differential mode noise

Differential mode noise occurs when unwanted electrical signals appear between two conductors carrying a balanced signal, such as in audio or data cables. Instead of affecting each conductor individually, the noise appears equally but in opposite directions on both wires. When the device measures the difference between these signals, the noise cancels out, reducing interference. This type of noise can originate from external sources like electromagnetic interference or power line fluctuations. Proper shielding, twisted pair wiring, and good grounding help minimize differential mode noise, ensuring cleaner signal transmission and better overall performance.
