differential mode interference

Differential mode interferences can occur in balanced and unbalanced circuits, namely when push-pull voltages

or push-pull currents are generated by an unbalance. Push-pull interference is coupled magnetically, electromagnetically or galvanically to the circuit lines, superimposed on the actual useful signals, which it thus impairs

. Thepropagation on the circuit lines is in the same direction as the useful signals.

Push-pull interference signals are caused by faulty earthing, asymmetries in circuits, incorrect conductor routing, non-twisted lines or signal conversions. Unlike common-mode interference, push-pull interference can be eliminated by circuitry measures, modified cable routing or other ground connections.
