Frekvenciaanalízis
Frekvenciaanalízis, commonly known as frequency analysis, is a mathematical technique used to decompose a signal or a function into its constituent frequencies. This process reveals the amplitude and phase of each frequency component present in the original signal. It is a fundamental tool in many scientific and engineering disciplines, providing insights into the underlying structure and behavior of various phenomena.
The most common method for performing frequency analysis is the Fourier transform. The discrete Fourier transform
Applications of frequency analysis are widespread. In signal processing, it is used for filtering, noise reduction,
