  "term": "Time-frequency analysis",
  "field": "Industrial and trades",
  "definition": "A set of signal processing techniques used to characterize how the frequency content of a signal changes over time. Unlike Fourier analysis, which provides an average frequency spectrum, these methods produce a two-dimensional representation showing spectral components at different moments. Common methods include the short-time Fourier transform (STFT), wavelet transforms, and the Wigner-Ville distribution, which are applied in fields like vibration analysis, acoustics, and communications.",
