värvispektri
Värvispektri is a term used primarily in Swedish technical literature to describe a particular method of spectral analysis applied to time‑varying signals. The word is a compound of *värv*, meaning “to blend” or “to mix,” and *spektri*, the Swedish form of “spectrum.” It refers to a process in which a signal’s frequency components are blended across a range to produce a smoothed or averaged spectral representation. This technique is especially common in the fields of signal processing, acoustics, and seismic data interpretation where it aids in reducing spectral leakage and emphasizes broader frequency trends rather than precise spectral peaks.
The method typically involves segmenting a time‑domain signal into overlapping windows, applying a Fourier transform to
Värvispektri has found use in oceanography for analyzing wave spectra, in engineering for vibration monitoring of
Because of its emphasis on blended variability, värvispektri is not a replacement for high‑resolution spectral methods
