korkeataajuisen

Korkeataajuisen is a Finnish inflected form of the adjective korkeataajuinen, meaning "high-frequency" or "of high frequency." The base adjective is formed from korke(a) ("high") and taajuus ("frequency"), with the adjectival suffix -inen; the form korkeataajuisen is the genitive singular (used after nouns, in possessive constructions and certain postpositional phrases) and also appears as the stem in some compound or inflectional contexts.

Usage and grammar

As an adjectival form, korkeataajuisen modifies nouns to indicate that the subject or object has high frequency characteristics (for example korkeataajuisen signaalin — "of the high-frequency signal"). In Finnish syntax the adjective agrees with the noun in case and number, so other inflected forms include korkeataajuinen (nominative singular) and korkeataajuista (partitive). The word commonly appears in technical fields such as acoustics, radio communications, electronics and signal processing to describe sounds, electromagnetic waves and signals that occupy the upper part of a frequency range.
