Keskfrekwents

Keskfrekwents is a term used in some telecommunications and signal-processing contexts to denote the central or midpoint frequency within a defined frequency band. The word is a compound formed from a root meaning center and frequency, and appears mainly in multilingual or Esperanto-inspired technical glossaries. It is not a universally standardized term in English-language literature; more often engineers speak of center frequency or carrier frequency.

In practice, keskfrekwents refers to the frequency around which a bandpass filter is centered or around which a modulated signal is spectrally concentrated. It is used when specifying channels, selecting LO (local oscillator) frequencies, or describing the central value in spectral analyses. The central frequency is related to, but distinct from, the bandwidth, which defines the width of the passband.

Determination of keskfrekwents can be done by measuring the frequency response of a system with a spectrum analyzer and identifying the midpoint between the band edges, or by calculating the arithmetic mean of the lower and upper edges of a defined band. In digital signal processing, the central frequency is often an important parameter in designing filters, modulators, and equalizers to ensure proper alignment with other system components.

Because keskfrekwents is not a standard term in many references, engineering documents may adopt more common terminology such as center frequency or carrier frequency. Its exact interpretation can vary by language and field.
