Pulse amplitude selector

{
  "id": "MLC-T-CHM-009670",
  "term": "Pulse amplitude selector",
  "field": "Chemistry",
  "definition": "A circuit that permits the passage of electrical pulses only if their amplitude falls within a specified range. It acts as a filter, allowing signals above a certain lower threshold and below an upper threshold to pass through. This device is used in nuclear counting to discriminate against noise or unwanted radiation events.",
