During the process of sending a signal through a circuit, the idea is to let the desired signal go through while filtering out other, unwanted signals.

One type of unwanted signal is common-mode noise, which is filtered out by a common-mode choke coil. Power lines are an example of a source of common-mode noise. Without a coil, the power line would create a lot of electrical noise as it traveled to its destination, which would then be received on the other end and possibly cause interference with the signal.

The choke coil works because it acts as an inductor. When the current passing through changes, as AC currents do, it typically creates a magnetic field in the coil that works against that current.

This property, known as inductance , blocks most of the AC current from passing through. Book Chosen Physics Part I. Subject Chosen Physics. Book Store Download books and chapters from book store.
