Automotive systems can be sources of radiated emissions that may affect on-board electronics, or interfere with electronic systems on adjacent vehicles or devices along the roadside, such as televisions, radios, etc. Active electronic devices generate radiated emissions during their normal operation because of switching operations, logic gates, PWM (pulse-width-modulated) control signals, etc. Even the non-solid-state components, such as mechanical switches, horns, relays, other inductive devices, and spark plugs can also radiate. Many of these devices have been used since the early days of the automotive industry, and still require attention to ensure that measures are taken to prevent problems.
