Electromagnetic energy where the frequency of oscillation of the energy lie in the region of 1 to 300 Hertz (Hz).
(ELF). That portion of the radio frequency spectrum from 30 to 3000 hertz.
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.
A signal in the frequency in the range from 30 to 300 kHz.
The band of frequencies up to 300 hertz.
(Abbreviated ELF.) See radio frequency band.
Extremely low frequency (ELF) is the band of radio frequencies from 3 to 30 Hz. ELF was used by the US Navy and Soviet/Russian Navy to communicate with submerged submarines.
