sagedusega

Sagedusega is a grammatical form in Estonian derived from the noun sagedus, meaning frequency. It represents the instrumental/comitative case and is used to express the frequency at which something occurs, is measured, or operates. The form is created from the genitive singular sageduse plus the comitative suffix -ga, yielding sagedusega.

In technical and scientific writing, sagedusega is common for stating operating conditions, signal properties, or measurement results. It is typically followed by a numeral and a unit, such as Hz, kHz, MHz, or GHz. For example, the phrase Seade töötab sagedusega 50 Hz means that the device operates at a frequency of 50 Hz. Another example is Heliomaduste kirjeldamisel võivad märgitakse sagedusega umbes 1 kHz, describing an approximate frequency.

The plural form sagedustega is used when referring to multiple frequencies or multiple measurements. This form follows the same pattern and is found in contexts where several signals or bands are discussed simultaneously.

Sagedusega is primarily a linguistic and stylistic tool in Estonian, especially in technical and scientific prose. In everyday speech, speakers may prefer the simpler construction sageldus on or to state the value more directly, such as sagedus on 50 Hz, without using the instrumental form. The English equivalents are to say “at a frequency of” or “with a frequency of.”
