aikataajuustila
Aikatataajuustila refers to the representation of a signal or data in the form of its frequency components over time. It is a fundamental concept in signal processing and analysis, providing insights into how the spectral content of a signal changes dynamically. Unlike a simple frequency spectrum, which shows the overall distribution of frequencies in a signal, the time-frequency representation captures how these frequencies evolve over time.
Common methods for generating time-frequency representations include the Short-Time Fourier Transform (STFT), the Wigner-Ville distribution, and
Time-frequency analysis is widely applied in various fields. In audio processing, it's used for speech recognition,
