korkeataajuisten

Korkeataajuisten is the genitive plural form of the Finnish adjective korkeataajuinen, which means high-frequency. It is used to describe a noun in the genitive case, signaling that the noun belongs to or is characterized by high frequency. In Finnish, adjectives agree with the nouns they modify in number and case, so korkeataajuinen forms into korkeataajuisten when the noun it describes is plural and in the genitive.

The adjective korkeataajuinen is a compound built from korkea (high) and taajuus (frequency) with the commonly used suffix -inen to form an adjective. The genitive plural ending -isten reflects a plural noun phrase in the genitive, for example korkeataajuisten signaalien (of high-frequency signals) or korkeataajuisten laitteiden (of high-frequency devices).

Korkeataajuisten commonly appears in technical and scientific Finnish, particularly in fields such as electronics, telecommunications, physics, and signal processing. It functions as a descriptive modifier rather than a standalone technical term. The form is most often encountered in formal or written Finnish, where precise grammatical case marking is used.

In usage, one would typically pair korkeataajuisten with a noun in genitive plural or with a noun in a related case, choosing the nominative plural korkeataajuiset when the subject is plural and not in the genitive. Examples include phrases like korkeataajuisten signaalien käsittely (processing of high-frequency signals) or korkeataajuisten laitteiden suunnittelu (design of high-frequency devices).
