frekvenciadomainon
Frekvenciadomainon is a term that appears in some discussions of signal processing to denote the frequency-domain perspective or methodology used to analyze and manipulate signals. It is not a widely standardized name for a specific theory or algorithm, but rather a conceptual label for approaches that focus on spectral content rather than time-domain waveforms.
In this view, signals are represented by their spectra, and the primary mathematical tool is the Fourier
Common techniques associated with frekvenciadomainon include windowing for spectral estimation, and methods such as the periodogram
Applications span audio processing (equalization and noise reduction), communications (channel characterization and filter design), image processing
