Frekvenciadoménbl

Frekvenciadoménbl refers to the representation of a signal or data in the frequency domain. Instead of viewing a signal as a function of time, it is analyzed by its constituent frequencies. This transformation is achieved using mathematical tools such as the Fourier Transform. In the frequency domain, a signal is described by its amplitude and phase at each frequency. This perspective can reveal characteristics of the signal that might be difficult to observe in the time domain. For example, periodic signals appear as distinct peaks at their fundamental frequency and harmonics. Noise, on the other hand, might be spread across a wide range of frequencies. The concept is widely applied in fields like signal processing, telecommunications, audio engineering, and image analysis. Analyzing signals in the frequency domain allows for tasks such as filtering unwanted frequencies, identifying the dominant frequencies, or compressing data by representing it more efficiently in terms of its spectral content. Different types of Fourier Transforms, such as the Discrete Fourier Transform (DFT) and the Fast Fourier Transform (FFT), are used for digital signals, enabling efficient computation of the frequency spectrum. The frequency domain provides a complementary view to the time domain, offering valuable insights and enabling powerful signal manipulation techniques.
