sagedusdomäänile
Sagedusdomäänile is a term used in Estonian-language contexts to denote the frequency-domain representation of a signal or the process of moving a signal from the time domain to the frequency domain. In signal processing, expressing a signal in terms of its frequency components can reveal periodic structures and spectral content that are not readily apparent in the time domain.
Transformations commonly used to achieve sagedusdomäänile include the Fourier transform for continuous-time signals, the Fourier series
In the frequency domain, a signal is represented by a spectrum X(f) that shows the amplitude and
Practical considerations in sagedusdomäänile analysis include sampling rate and the Nyquist criterion to avoid aliasing, windowing
Applications span audio and image processing, communications, system identification, filtering, and spectrum analysis. Understanding the frequency-domain
