filtrovat

Filtrovat is a Czech verb meaning to filter. It denotes the act of passing a substance, signal, or dataset through a filter or through criteria in order to separate unwanted parts, reduce noise, or narrow results. The process can be physical, such as filtering liquids or air, or abstract, such as filtering information, content, or data. The related noun is filtrace, and the object used for filtration is a filtr (or filter).

Etymology and form: filtrovat is formed from the noun filtr by attaching the Czech verbal suffix -ovat, a productive pattern for creating verbs from nouns. The noun filtr itself is borrowed from other European languages, such as German, English, or French, with a similar word for the filter in those languages. This reflects a common cross-linguistic origin for the concept of filtration.

Applications and usage: In science and industry, filtrovat describes the physical separation of solids from liquids or gases, as in filtering a solution or filtering air. In information technology and everyday language, it refers to applying criteria to exclude or select items, for example filtrovat data sets, filtrovat vyhledávací výsledky, or filtrovat obsah na internetu. It is also used in signal processing to filtrovat šum, or in communications to filtrovat nežádoucí signály. The term is commonly paired with the noun filtr or the noun filtrace to describe the mechanism or the process.
