In telecommunication, the term common-mode interference has the following meanings:
- Interference that appears on both signal leads (signal and circuit return), or the terminals of a measuring circuit, and ground.
- A form of coherent interference that affects two or more elements of a network in a similar manner (i.e., highly coupled) as distinct from locally generated noise or interference that is statistically independent between pairs of network elements.
Techniques for dealing with common-mode interference
Common mode noise may be isolated from the desired signal by various means:
