High frequency limit — The high frequency limit of hearing is the upper extent to which a particular animal can perceive sound. Perhaps the most commonly known aspect of the psychoacoustic model is that humans cannot hear frequencies above and below certain thresholds; … Wikipedia
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.ExplanationBecause of the electrical conductivity of salt water, submarines are shielded from… … Wikipedia
Low-pass filter — A low pass filter is a filter that passes low frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter … Wikipedia
Frequency — For other uses, see Frequency (disambiguation). Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s) … Wikipedia
Frequency extender — In broadcast engineering, a frequency extender is an electronic device that allows high fidelity analogue audio to be sent over regular POTS telephone lines, without the loss of higher audio frequencies (treble). It is an extended concept of a… … Wikipedia

Low-power electronics — means that the consumption of electric power is deliberately low, e.g. notebook processors. Electronics The density and speed of integrated circuit computing elements has increased roughly exponentially for a period of several decades, following… … Wikipedia
Low-carbohydrate diet — Low carbohydrate diets or low carb diets are dietary programs that restrict carbohydrate consumption usually for weight control or for the treatment of obesity. Foods high in digestible carbohydrates (e.g. bread, pasta) are limited or replaced… … Wikipedia
