Low frequency electromagnetic waves that emanate from electromechanical devices. An electromagnetic disturbance caused by such radiating and transmitting sources as heavy duty motors and power lines can induce unwanted voltages in electronic circuits, damage components and cause malfunctions. See: radio frequency interference.
Interference caused by the radiation of an electric or magnetic field.
EMI is any energy that interferes with the normal operation of equipment. EMI can be radiated or conducted. Equipment lock-up is often misdiagnosed as a software or hardware problem, when ESD-induced EMI may be the true culprit.
A disruption caused by energy fields. An ICD can be affected by these fields if they are very strong, causing the ICD to either pause its normal operation or deliver an inappropriate therapy. If you move away from the source of EMI, your Medtronic ICD will return to its normal operation.
an unwanted (possibly interfering) signal emitted by any electronic apparatus. The emission of EMI is heavily regulated in most countries.
An effect of undesirable energy. EMI is typically emitted by switching power supplies, and may be conducted or radiated.
Sources are sparks, lightning, radar, radio and TV transmission. EMI can cause undesirable voltage signals.
Interference to any electronic device caused by a producer of electromagnetic energy.
Radio frequency energy that interferes with the operation of a device. This radio frequency energy may be produced by the device itself or by other devices nearby.
EMI covers the influencing of a systems performance due to radiated or conducted electro- magnetic (electric field and magnetic fields) radiation.
Any electrical or electromagnetic phenomenon, manmade or natural, either radiated or conducted, that results in unintentional and undesirable responses from, or performance degradation or malfunction of electronic equipment.
Any conducted, radiated, or induced voltage which degrades, obstructs, or repeatedly interrupts the desired performance of electronic equipment. The lack of EMC, since the essence of interference is the lack of compatibility. EMI is the process by which disruptive electromagnetic energy is transmitted from one electronic device to another via radiated or conducted paths (or both). In common usage, the term refers particularly to RF signals. EMI can occur in the frequency range commonly identified as "anything greater than DC to daylight."
An unwanted signal that enters the transmission line from fluorescent lights, fan motors, etc. See also RF Interference.
Electromagnetic energy that causes interference in the operation of electronic equipment. Can be conducted, coupled or radiated. Can be natural or man-made.
Electromagnetic waves that interrupt signals in electronic equipment. A common example is the electromagnetic waves generated by lightning that cause noise in radio or TV signals.
Unwanted electrical or electromagnetic energy that causes undesirable responses, degrading performance or complete malfunctions in electronic equipment. See also: noise.
(EMI): produced by an electromagnetic field. If it is strong enough, it may interfere with the operation of an AICD system; this happens only on very rare occasions.
Electromagnetic phenomena which, either directly or indirectly, can contribute to a degradation in performance of a electronic system. (The terms radio interference, noise, EMI and RFI have been employed at various times in the same context).
an electromagnetic disturbance that degrades or limits the effective performance of electronic or electrical equipment.
The temporary interference in the normal operation of an implanted device due to the presence of an electromagnetic field.
Any electronic disturbance that interrupts, obstructs, or otherwise impairs the performance of electronic equipment. For power supplies, unwanted energy, generally emitted from switching power supplies, which may be conducted or radiated.
The interference caused by an electromagnetic field created by the flow of current. also see: AKA: Antonym: Source: http://www.the12volt.com/glossary/glossary.asp
Electrical or magnetic energy that is strong enough to interfere with or disrupt your therapy.
The interference, generally at radio frequencies, that is generated within the system (in this case the car), as contrasted to RF interference coming from sources outside the system.
(EMI)-Electrical interference that can cause equipment to work improperly. EMI can be separated into conducted EMI (interference conducted through cables out of the UPS) and radiated EMI (interference conducted through the air).
Any magnetism produced by an electric charge in motion that interrupts, obstructs, or otherwise impairs the performance of electronic equipment.
This type of interference is caused by an electromagnetic field generated close to your system or anywhere between the power/signal source and your home. A washing machine, vacuum cleaner, or blender (yours or a neighbor's!) can add a loud buzzing or a barely audible low frequency hum to your audio system and distort your TV picture.
Electromagnetic emissions from a device or system that interfere with the normal operation of another device or system.
Electrical or electromagnetic energy that disrupts electrical signals.
Radio Frequency Interference (RFI) is electromagnetic radiation which is emitted by electrical circuits carrying rapidly changing signals, as a by-product of their normal operation, and which causes unwanted signals (interference or noise) to be induced in other circuits. The FireWire color logo
EMI - An unwanted electrical energy in any form. EMI is often used interchangeably with 'noise' and 'interference'.
Also known as "radio-frequency interference (RFI)," it is unwanted high frequency energy conducted through the input or output lines of switching power supplies or radiated through space. EMI is caused by the switching transistors, output rectifiers and zener diodes.
Interference caused when the radio waves of one device distort the waves of another. Cells phones, wireless computers and even robots in factories can produce radio waves that interfere with RFID tags.
Any electromagnetic disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics/electrical equipment. It can be induced intentionally, as in some forms of electronic warfare, or unintentionally, as a result of spurious emissions and responses, intermodulation products, and the like. EMI is also an engineering term used to designate interference in a piece of electronic equipment caused by another piece of electronic or other equipment. EMI sometimes refers to interference caused by nuclear explosion. Synonym: radio frequency interference.
occurs when some device in a person's environment emits electromagnetic energy that is not compatible with the sensitive electronics incorporated into many medical devices such as power wheelchairs. This causes the wheelchair to behave abnormally. For example, a cellular phone can interfere with the controller of the power wheelchair so that the chair moves unexpectedly or erratically.
Man-made or natural interference that degrades the quality of reception of radio waves.
Any electromagnetic disturbance, or emission that causes undesired responses or degradation of performance in electrical or electronic equipment.
Electrical and magnetic noise imposed on a system. There are many possible causes, such as switching AC power on inside the sine wave. EMI can interfere with the operation of controls and other devices.
Every electric current that flows produces a magnetic field. If the current increases or decreases, the magnetic field grows or shrinks. If this moving magnetic field passes through a wire, a voltage signal will be induced in the wire which may interfere with the correct operation of the circuit of which the wire forms a part. Strong magnetic fields occur where cables carry heavy current, so special attention must be given, for example, to the design of the computer's power supply. If electric currents are changing rapidly, radio waves can be generated which may cause interference with other equipment. [EMC, RFI
Abbreviated EMI. Any electromagnetic radiation released by an electronic device that disrupts the operation or performance of any other device. ... more
