  • Term
    Definition
  • The unintentional release of electromagnetic energy from an electronic device or apparatus.
  • Ability to withstand electromagnetic energy that arrives via free-space propagation.
  • The determination or measurement of a device's capability to function in the presence of undesirable radiated EMI from external electromagnetic sources.
  • The Radio Equipment Directive (RED) (2014/53/EU) ensures a Single Market for radio equipment by setting essential requirements for safety and health, electromagnetic compatibility, and the efficient use of the radio spectrum. It applies to all products using the radio frequency spectrum and(...)

  • Rate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.
  • Rate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.
  • Ability of antenna-connected RF receiver and transmitter subsystems operating within a system to function properly without performance degradation caused by antenna-to-antenna coupling.
  • Also known as Electromagnetic Interference. A disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
  • Also known as Electromagnetic Interference. A disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
  • A US volunteer organization that develops technical guidance for use by government regulatory authorities and by industry. It has over 200 committees and overall acts as an advisory body to the FAA.

  • This column is comprised of a “lessons-learned” editorial approach and contributed by readers anxious to share their trials and tribulations in compliance engineering.
  • An electronic device that converts a signal from a modulated radio wave into usable information.
  • a method of restoring a signal’s high-frequency components that the media preferentially attenuates
  • An electrical device that converts an alternating current into a direct one by allowing a current to flow through it in one direction only.
  • An electrically operated switch.
  • An area of study focused on optimizing the reliability, or probability of successful functioning, of systems, such as airplanes, linear accelerators, and any other product.
  • Property of a conductor due to which it opposes the flow of current through it.
