As of May 31, 2023, we have updated our Code of Conduct.

Questions with this tag are about the symptoms, causes and cures of interference, which is defined as an undesirable electrical phenomenon competing with a desirable electrical signal(s).

Electrical energy is used in many forms:

  • DC Direct current, as from a battery
  • AC Alternating current, as from our power grid (high energy) or a microphone (low energy)
  • Ionized particles, x-rays, gamma rays, beta particles
  • Electromagnetic radiation, as in radio, transformers, microwave

Interference is the contamination of information/energy such that the original information/energy is less useful. Impairment may range from nuisance (static on an AM radio) to catastrophic (loss of life due a control system being disabled).

Use this tag when asking questions about the symptoms of interference, possible causes of interference, and possible cures.
