  "term": "Discriminator",
  "field": "Chemistry",
  "definition": "An electronic circuit that produces an output signal only when the input signal exceeds a predetermined threshold voltage. It is used to filter out noise or unwanted low-amplitude signals from a detector's output. This device is commonly employed in nuclear counting systems to select pulses corresponding to specific energy ranges.",
