Eleven Categories of Line Noise
3. Cross-talk
- occurs when a circuit picks up signals in another (e.g., hearing another telephone conversation in the background)
- occurs
- between line pairs that are carrying separate signals,
- in multiplexed links carrying many discrete signals,
- in microwave links in which one antenna picks up a minute reflection from another antenna
- in any telephone circuits that are too close to each other or are not electrically balanced
- cross talk increases with
- increased communication distance
- increased proximity of the two wires
- increased signal strength
- higher frequency signals
