Definition von radio frequency im Englisch Englisch wörterbuch: A frequency in this range; That part of the electromagnetic spectrum, between about 3 kHz and 300 MHz, within which radio waves are transmitted; Radio frequency refers to a signal generated by a radio transmitter and sent out through an antenna The frequency of the transmission is described in terms of the number of cycles per second or Hertz (Hz) A radio would be tuned to this frequency in order to receive the transmission A radio signal is sometimes referred to by its initials, "RF"; A generic term for radio-based technology; Frequency in the portion of the electromagnetic spectrum between audible frequencies and infrared frequencies Present practical limits are roughly 10 kilohertz to 100,000 megahertz; RF (as oposed to IF) refers to the incoming frequency or band of frequencies being studied In an heterodyne receiver the RF is mixed down to an IF band In bolometers the RF band is measured directly; A frequency at which coherent electromagnetic radiation of energy is useful for communications Radio frequencies are designated as very low: <30 kHz, low: 30 to 300 kHz, medium: 300 to 3,000 kHz, high: 3 to 30 MHz, very high: 30 to 300 MHz, ultrahigh: 300 to 3,000 MHz, superhigh: 3 to 30 GHz, and extremely high: 30 to 300 GHz; Waves transmitted in the range within which radio waves may be transmitted; Any frequency that corresponds to radio signals, including those used by cellular telephones and wireless networks; The area (or band) of the electromagnetic spectrum where most radio communication takes place, typically from 100 KHz to 100 GHz; A frequency band in the electromagnetic spectrum with frequencies in the millons of cycles per second [Chapter 3]; Electromagnetic carrier waves upon which audio, video, or data signals can be superimposed for transmission; The frequencies in the electromagnetic spectrum that are used for radio communications; On-line communication of data using radio-equipped computers; RF for short That part of the spectrum from approx 50kHz to gigahertz; GHz, MHz, Hz The international unit for measuring frequency is Hertz (Hz), which is equivalent to the older unit of cycles per second One Mega-Hertz (MHz) is one million Hertz One Giga-Hertz (GHz) is one billion Hertz For reference: the standard US electrical power frequency is 60 Hz, the AM broadcast radio frequency band is 0 55 -1 6 MHz, the FM broadcast radio frequency band is 88-108 MHz, and microwave ovens typically operate at 2 45 GHz; (RF) The frequencies in the electromagnetic spectrum that are used for radio communications; The group of electromagnetic wavelengths between 500 KHz and 300 GHz These wavelengths are used to transmit data or voice signals through the air, to avoid dependence on terrestrial wire transmissions; That portion of the electromagnetic spectrum extending from 500,000 cycles per second (500 kHz) to 500 million cycles per second (500 MHz); Any frequency within the electromagnetic spectrum normally associated with radio wave propagation (188) For designation of subdivisions, see electromagnetic spectrum and associated diagram; an electromagnetic wave frequency between audio and infrared; The frequencies of the electromagnetic spectrum normally associated with radio wave propagation Sometimes defined as any frequency at which transmission of coherent electromagnetic energy radiation is possible Any frequency at which electromagnetic radiation is useful for telecommunication; Typically a frequency from 20 kHz to 3 GHZ RF is usually referred to whenever a signal is radiated through the air Literally, any and all frequencies that can be radiated as an electromagnetic wave; frequency of wavelength of a radio wave; That group of electromagnetic energy whose wavelengths are between the audio and the light range Electromagnetic waves transmitted usually are between 500 KHz and 300 GHz; That part of the spectrum from approximately 50kHz to gigahertz; Any ac frequency at which coherent electromagnetic radiation of energy is possible Usually considered to denote frequencies above 150 kilohertz and extending up to the infrared range; one suitable for radio transmission, about 10^4 Hz and below 3 X 10^12 Hz; Non-optical automatic identification devices that use radio waves to transmit data; rf
radio frequency integrated circuit: An integrated circuit containing analog circuitry operating at frequencies in and above the ultrahigh frequency band
Radio Frequency Identification: {i} RFID, automatic electronic tracking and identification system for storing information sent by radio waves and remote retrieval of data using tags or small labels used to track movement of merchandise or parcels and baggage (the system was originally developed to track cattle)
radio frequency automatic identification: (Ticaret) (RFID) A location and identification system using radio frequency signals that employs a transceiver, antenna and tag associated with a product and location to transmit data. The systems do not require a direct line of sight or contact and can transmit at high speed, but are more costly than other data collection technologies such as bar coding. RFID systems are often used for inventory tracking in large warehouse and distribution center facilities
radio frequency identification: The process of using an electrical transponder which stores information that can be used to identify the item to which the transponder is attached, similar to the way in which a bar code on a label stores information that can be used to identify the item to which the label is attached
radio frequency identification: A method of reading a card using radio frequency energy to transmit information from the card to a reader See Proximity
radio frequency identification: The use of small radio transponders which are activated by a reading transmitter The transponder can carry a unique ID code or other information in its memory, and can be read at a distance without line of sight
radio frequency interference: Radio signals from external sources that invade and can be heard through, sound systems
radio frequency interference: Electromagnetic interference originating in the radio frequency bands
radio frequency interference: 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
radio frequency interference: (EFI/RFI) A form of "noise" on data transmission mediums that can reduce data integrity & increase transmission errors
radio frequency interference: EMI in electronic equipment caused by radio frequencies, ranging typically from 10 kHz (104 Hz) to 1000 MHz (109 Hz or 1 GHz)
radio frequency interference: Disruption of the signal by radio waves at the same frequency as the desired signal
radio frequency interference: 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
radio frequency interference: 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
radio frequency interference: Synonym electromagnetic interference
radio frequency interference: The unintentional transmission of radio signals Computer equipment and wiring can both generate and receive RFI See also electromagnetic interference
radio frequency 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-frequency: Of or pertaining to electromagnetic radiation in the radio frequency band of the spectrum
radio-frequency identification: The storage and retrieval of data using tags attached to individual packages, animals or people; the tags contain an integrated circuit to store and process the data, and an antenna to transmit and receive such data
Radio-frequency: rf
radiofrequency: alternative spelling of radio-frequency
