High-pass filter

{
  "id": "MLC-T-CHM-005297",
  "term": "High-pass filter",
  "field": "Chemistry",
  "definition": "An electronic filter that allows signals with frequencies higher than a certain cutoff frequency to pass through, while attenuating signals with frequencies lower than the cutoff. This type of filter is used to remove low-frequency noise or baseline drift from analytical signals. Its performance is characterized by its cutoff frequency and roll-off rate.",
