RFI. Many electronic devices, including computers and peripherals, can interfere with other signals in the radio-frequency range by producing electromagnetic radiation; this is normally regualated by government agencies in each country.
Undesired signals received by a user; those signals that miss their desired user become interference energy to users in the same or adjacent cells.
Noise caused by the presence or radio frequency electro-magnetic waves which adversely affect audio components.
Any electrical signal capable of interfering with the operation of electrical or electronic equipment.
Noise induced upon signal wires by ambient radio-frequency electromagnetic radiation with the effect of obscuring an instrument signal.
Degrades sound quality. Often caused by placing an audio component near a TV, which generates RFI.
Interference to any electronic device caused by a producer of RF.
Radio frequency is the electromagnetic spectrum from 3 KHz to 300 GHz.
A form of electromagnetic interference created in the ignition secondary circuit, alternator, or cycling electrical circuits which disrupts radio transmission.
RFI is commonly generated by devices that switch the output power at some voltage other than zero. Typically, phase-angle fired SCRs may generate RFI while zero-cross fired SCRs virtually eliminate RFI.
RFI is manmade or natural, intentional or unintentional electromagnetic propagation which results in unintentional and undesirable responses from or performance degradation or malfunction of, electronic equipment.
Often synonymous with electromagnetic interference, RFI is a frequency range containing coherent electromagnetic radiation of energy useful for communication purposes—roughly the range from 10 kHz to 100 GHz. This energy may be transmitted as a byproduct of an electronic device's operation. RF is transmitted through two basic modes: Radiated emissions: The component of RF energy that is transmitted through a medium as an electromagnetic field. RF energy is usually transmitted through free space; however, other modes of field transmission may occur. Conducted emissions: The component of RF energy that is transmitted through a medium as a propagating wave, generally through a wire or interconnect cables.
Typically experienced as "snow" in a TV screen or "pops" in your speakers, there are numerous sources of radio interference. Some sources are nearby like CB or Ham radios, or cell phones. Other sources can be far away like radio stations, microwave towers and the like.
EMI in electronic equipment caused by radio frequencies.
(Abbr. RFI) High-frequency electromagnetic waves that emanate from electronic devices such as chips.
Any electromagnetic disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics/electrical equipment.
Noise caused by devices producing electromagnetic radiation in the radio frequency range.
Electromagnetic waves that cause interruptions of signals processed in radios.
(RFI): Interference to the radio frequency band caused by other high frequency equipment or devices in the immediate area. Fluorescent lighting systems generate RFI.
An audible buzz or noise in some sensitive audio and radio equipment caused by the dimmer's rapid current switching in conjunction with sharp current rise.
can cause specific breath testing apparatus to render false results. Although newer breath test machines may be equipped with an RFI detector, these detectors are not reliable.
Interference from outside the system or systems, as contrasted to Electromagnetic Interference (EMI ), which is generated inside the system.
An unwanted electrical signal that travels through the air or follows the path of a conductor and interferes with communications. Some common causes of RFI include light dimmers, fluorescent lights, variable frequency drives, and computers.
An undesired radiated or conducted signal in the radio frequency spectrum.
This type of interference results from radio waves that can be generated by radio stations, microwaves, cell phones, lawn mowers, generators, CB radios, and many other sources. Often originating a great distance from your home, these patterns of interference can be heard as clicks, pops, and sometimes even unwanted voices, and can be seen as "snow" on your TV's picture.
A type of system noise caused by communication system components.
A signal (noise) that is radiated or conducted from one electronic circuit or device the may cause incorrect operation interference in another electronic circuit or device. An electronic circuit or device can be an emitter of electromagnetic interference (EMI) or susceptible to electromagnetic interference.
A term used to denote apparent disturbance or distortion to satellite signals. Abbreviated RFI
Electromagnetic waves between the frequencies of 10 KHz and 300 GHz that can affect susceptible systems by conduction through sensor (tape head) or power input lines, and by radiation through space.
