Examples

  • And a high pass filter, of course, would pass high frequencies.

  • Abstract: Speech recognition scores in noise are improved for some subjects who wear hearing aids that reduce low-frequency noise with an adjustable high-pass filter circuit.

  • In this type of processing, the cutoff frequency of a high-pass filter moves lower in frequency as the amount of low-frequency energy decreases.

    Academic text (1990)

    Academic text (1990)

    Academic text (1993)
  • Further, monosyllabic speech recognition in noise testing indicated improvements in the performance of the hearing-impaired subjects related to the decrease of upward spread of masking in the high-pass filtering conditions.

    Academic text (1993)

Morphology

high-pass + filter

The meaning 'a filter that allows high frequencies to pass while attenuating lower ones' is directly compositional from 'high' + 'pass' + 'filter' — a device that lets high (frequency) signals pass. This follows a common technical naming pattern (cf. 'low-pass filter') and has clear cross-linguistic equivalents, so a B1 learner who knows the constituents can reasonably infer the meaning.

Etymology

The noun high-pass filter comes from the simple image of a gate that lets high sounds pass while the filter stops low sounds. So, it is a device that 'lets higher sounds through' and 'keeps out lower ones'.
