  "id": "MLC-T-MET-006153",
  "term": "Half-power points",
  "field": "Meteorology and atmospheric science",
  "definition": "The frequencies in a filter or resonant circuit where the output power is half of the maximum power. These points correspond to a reduction in voltage or current amplitude by a factor of 1/√2, or approximately 0.707, from the peak value. They define the bandwidth of the system, often expressed in Hertz.",
