I assume you mean for something like a car.
It can be as simple as a capacitor to as complex as total shielding for the engine.
The need is because spark plugs put out a random collection of radio frequencies,
in fact the first "radios" were just that: a kind of spark plug that ran short or long for dots and dashes. Everybody heard everybody else.
What else can I help you with?
What is meant by radio frequency interference?
Radio frequency interference (rfi) is simply either man-made or natural sources that interact with radio waves. A natural source - is the crackle you hear from your radio when there's a lightning storm between you and the transmitter. A man-made source - could be something like hearing a taxi-cab radio over a 'normal' radio program.
Which wireless standard is least prone to radio interference?
802.11a as it only operates on 5gz, a frequency that is generally unused by other devices.
Why does your radio whistle when you step on the gas...the whistle gets louder the more gas I give?
The alternator or coil needs suppressing. Electrical devices make radio frequency interference. Go to an I.C.E shop for best suppressor.
Interference between two radio signals to improve radio images?
Interferometry
Does XM radio have static interference?
XM radio does not have static interference. It's a digital signal, so you'll either get a crystal-clear sound or none at all.
What term is often used to describe interference of radio waves?
The term often used to describe interference of radio waves is "radio frequency interference" (RFI). RFI can disrupt the normal operation of electronic devices that rely on radio frequency signals for communication.
What kind of a filter do you need to stop static in a FM radio in a shop that has neon lights?
You probably need an RFI (Radio Frequency Interference) filter either between the neon lighting transformer and the wall plug, or a transformer with a built-in RFI filter.
What cable is NOT subject to electromagnetic interference or radio frequency interference?
Fiber-Optic
What are reasons for electrical interference on car radios?
Electrical interference in a car radio is the same as electrical interference on any radio. Radio interference is literally the sound of the air. When a radio signal is broadcast, the frequency that was previously only occupied by air is overpowered and drowned out, thus you hear the broadcast frequency clearly. When the broadcast frequency is weak (i.e. you are too far away or something is blocking the signal), the frequency cannot completely overpower the air and thus you hear some of both.
Is fiber optic immune to electromagnetic interference and radio frequency interference?
Yes. It is immune to EMF (electromagnetic interference) and does not create its own EMI. Also, it is immune to RFI, or radio frequency interference. This is because fiber optic carries signals as light waves instead of electrical impulses.
What is the word for the interference of radio waves?
The interference of radio waves is commonly referred to as "static" or "noise". This can be caused by various factors such as atmospheric conditions, electronic devices, or other radio frequency signals.
What is a RF Lead?
What is sometimes called a Radio Frequency lead is a shielded cable used beween pieces of equipement to reduce the effects of radio frequency interference.
What are the two types of interference often encountered when using copper media?
The two types of interference often encountered when using copper media are electromagnetic interference (EMI), caused by external electromagnetic fields disrupting signal transmission, and radio frequency interference (RFI), caused by unwanted radio frequency signals interfering with data transmission.
What is RFI filter and does it go with fuel filter for 99 escalade?
NOISY FUEL PUMPS CAN SOMETIMES GET PICKED UP BY THE RADIO (RADIO INTERFERENCE) RFI FILTERS MOUNTED ON FILTER SUPPRESS ANY ANNOYING FREQUENCY NOISE. I FOUND MY ANSWER BY GOOGLING MY QUESTION. 99 ESCALADE EXPORT MODEL HAS A RFI FILTER ; A NON-EXPORT MODEL DOES NOT. EXPORT MODEL HAS A CODE OF 'GFV' TAGGED ON PUMP AND HAS A RFI FILTER.
Why generate radio frequency in resonant cavity?
to filter out unwanted signals.
What is a snap choke core?
It is a ferrite core over coax cable, AC or audio cord. It prevents electro-magnetic interference (EMI) and cuts down on radio-frequency interference (RFI).Prevents electric magnetic interference (EMI) and cut down on radio frequency interference (RFI)Simply snap it over any coax cable, AC or audio cordRoSH compliant
What can you do when everyday at lunchtime wireless users complain of lack of connectivity?
reduce the radio frequency interference around the WAP
