Extremely Low Frequency. Electromagnetic energy where the frequency of oscillation of the energy lie in the region of 1 to 300 Hertz (Hz).
The term ELF is used in reference to electromagnetic fields having frequencies much lower than the frequencies of signals typically used in communications. The most common ELF field is radiated by utility power lines.
Extremely low frequency. For magnetic fields and alternating electric fields, the ELF fields range from 5Hz to 2Khz. mission - The emitting of different types of radio frequencies, magnetic fields and light.
Extremely Low Frequency electronics intelligence
Extremely Low Frequency. Frequency band in the range of 3 - 30 Hz, corresponding to wavelength from 100,000 km to 10,000 km. EHF band overlaps audio frequencies. Because of its wavelengths, it's almost impossible to make antenna and transmitter that works at this band.
Stands for Extremely Low Frequency usually referring to magnetic fields at 0.5 to 100 Hertz.
Extremely Low Frequency. For those concerned with reducing their exposure to the electromagnetic fields associated with electronic displays, conductive coatings provide shielding from ELF/VLF (electric field) radiation to help comply with TCO and MPRIII standards. We currently carry a matrix of Anti-Reflection/Conductive Windows.
Extremely Low Frequency. That portion of the radio frequency spectrum from 30 to 3000 hertz
Extra, or Extremely low frequency field at the end of the electromagnetic spectrum, from 30 to 300 Hz. The 60-Hz power frequency is in this ELF range.
Extremely low frequency, 3 to 300 Hz.
Extremely Low Frequency. A signal in the frequency in the range from 30 to 300 kHz.
Abbreviation for extremely low frequency. See radio frequency band.
display:(Extremely Low Frequency) A type of radiation given off by almost any electric device, but potentially dangerous amounts come from power lines, heavy machinery and some video monitors. The best prevention is to sit at arm's length from your monitor and stay away from the back or sides of one - that's where the radiation is highest. Shop for low-ELF displays.
