Time-frequency representation

  "id": "MLC-T-IND-006032",
  "term": "Time-frequency representation",
  "field": "Industrial and trades",
  "definition": "A mathematical or graphical depiction of a signal that simultaneously shows its energy distribution across both time and frequency axes. This representation is particularly useful for analyzing non-stationary signals, where frequency content varies over time. Examples include the short-time Fourier transform and the Wigner-Ville distribution, which provide insights into signal characteristics not visible in either domain alone.",
