EMI in electronic equipment caused by radio frequencies, ranging typically from 10 kHz (104 Hz) to 1000 MHz (109 Hz or 1 GHz)
Disruption of the signal by radio waves at the same frequency as the desired signal
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
(EFI/RFI) A form of "noise" on data transmission mediums that can reduce data integrity & increase transmission errors
Radio signals from external sources that invade and can be heard through, sound systems Reflection: A term that describes the amount of sound "bouncing" off of hard surfaces Rejection: A microphone's ability to selectively exclude sounds coming from outside it's pickup pattern Resistance: Opposition, measured in ohms, to the flow of electrical current Reverberation: Sound waves that continue to bounce around a space after the sound source has ended Room: Any enclosed space in which a performance is staged
The unintentional transmission of radio signals Computer equipment and wiring can both generate and receive RFI See also electromagnetic interference
Any induced, radiated, or conducted electrical disturbance or transient that causes undesirable responses or malfunctioning in any electrical or electronic equipment, device, or system Same as EMI
Radio signals from external sources that invade and can be heard through, sound systems
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
