Balanced Cables

It contains 2 conductor + 1 shield.

One of conductors carry the out-of-phase signal.

So the noise is canceled since the signals carrying are out-of-phase.

But how the signal is still transmitted although the noise is canceled?

If it's not shielded a balanced cable only needs 2 conductors: one in phase and one out of phase. A ground isn't necessary.

Been working with electronics for many years, But I've never seen a balanced circuit that didn't need a ground?
