Frekvensmässigt

Frekvensmässigt is a Swedish adverb used in technical or scientific writing to describe an analysis, comparison, or characterization that is based on frequency content rather than time or amplitude alone. The term translates roughly to "frequency-wise" or "in terms of frequency" in English.

Etymology and form: The form is built from frekvens (frequency) and the suffix -mässig or adverbial -mässigt, which in Swedish marks a relation to a characteristic (for example tidsmässig, kostnadsmässigt). This construction is common for describing how a result or observation relates to a particular criterion.

Usage: The expression occurs in fields such as signal processing, acoustics, linguistics, statistics, and meteorology. It is used to indicate that a property, comparison, or result is evaluated with respect to the frequency content or distribution. For example, "frekvensmässigt liknar de två signalerna varandra" means the two signals are similar in frequency content, and "frekvensmässigt dominerar energin vid låg frekvens" describes energy dominance at low frequencies. In practice, it is often linked with terms like frekvensdomän or spektrum, as in discussions of data in the frequency domain rather than the time domain.

Relationship and scope: The adverb is one of several Swedish forms used to discuss data by a specific criterion; it is not a general term for frequency-related properties, but specifies the basis of comparison. It is most common in formal texts and technical reports, where precision about analytical perspective is important.
