høyfrekvente

Høyfrekvente is a Norwegian term meaning high frequency. It describes phenomena characterized by rapid oscillations or high repetition rates, typically measured in hertz. The exact threshold for what counts as high frequency varies by context and field, so there is no universal cutoff.

In technology and communications, høyfrekvente refererer to signals and components that operate at relatively high radio frequencies. In RF engineering, several broad bands are commonly noted: high frequency (HF) roughly 3–30 megahertz, very high frequency (VHF) 30–300 megahertz, and ultra high frequency (UHF) 300 megahertz to 3 gigahertz. The term is often used to describe transmitters, receivers, filters, and antennas designed for these ranges. In audio and electronics, it can also describe signals with frequencies above the upper limit of human hearing, or components designed to handle such frequencies.

In medicine, høyfrekvente omkring ultralyd referer to ultrasonic frequencies, typically in the megahertz range. Diagnostic ultrasound uses about 2–15 MHz; higher frequencies yield better image resolution but shallower penetration, while lower frequencies penetrate deeper with lower resolution.

In linguistics and corpus linguistics, høyfrekvente ord are the most common words used in a language or dataset. These words appear frequently across texts and speech and are often distinguished from low-frequency terms in studies of language use, vocabulary acquisition, and information retrieval.

Overall, the concept of høyfrekvente is domain-specific, indicating frequency levels that are high relative to a given standard within a field.
