Vysokofrekvenními

Vysokofrekvenčními is the instrumental plural form of the Czech adjective vysokofrekvenční, meaning “high-frequency.” It is used to modify nouns in the instrumental case, for example s vysokofrekvenčními zařízeními (with high‑frequency devices) or vysokofrekvenčními signály (high‑frequency signals).

In technical and scientific contexts, the term designates properties, technologies, or methods that operate at high radio or microwave frequencies. It frequently appears in discussions of electronics, telecommunications, and related fields, as well as in certain medical and industrial applications that employ high‑frequency energy. Examples include high‑frequency devices, high‑frequency procedures, or high‑frequency methods described as vysokofrekvenčními technikami or použitými vysokofrekvenčními metodami.

Etymology and usage notes: the word combines vysoký (high) with frekvence (frequency) and the suffix -ční, yielding an adjective meaning “high-frequency.” Its instrumental plural form, vysokofrekvenčními, follows Czech declension rules for adjectives and is used when the described nouns appear in the instrumental plural (e.g., zařízeními, metodami, signály). The exact nuance depends on the accompanying noun, but the core idea remains the same: the subject involves high-frequency energy or characteristics.
