Frecvenelor

Frecvenelor is the non-diacritic representation of the Romanian genitive plural frecvențelor, meaning “of the frequencies.” It is used in technical writing to refer to the set or collection of frequencies that comprise a signal or spectrum. Although frecvențelor is the standard form with diacritics, frecvenelor appears in ASCII texts and contexts where diacritics are omitted.

In scientific and engineering contexts, frecvenelor appear in phrases such as spectrul frecvenelor (the spectrum of frequencies) or banda de frecvențe (a band of frequencies). The analysis of frecvenelor typically involves transforming a time-domain signal into the frequency domain using Fourier analysis, such as the Fourier transform or Fourier series, and estimating spectral density. The frecvenelor are measured in hertz (Hz) and its multiples, such as kHz, MHz, and GHz, and their distribution informs filtering, modulation, and bandwidth planning.

In music and acoustics, frecvenelor determine pitch, timbre, and harmonic content; the overtone series describes how higher frecvenelor relate to a fundamental frequency. The distinction between frecvență (singular) and frecvențe (nominative plural) versus frecvenelor (genitive plural) is a matter of grammatical case in Romanian texts, and the non-diacritic form frecvenelor is common in ASCII documents.

Related terms include frecvență, frecvențe, spectru de frecvențe, transformata Fourier, and analiză spectrală.
