Noun

[edit]

filter (plural filters)

  1. A device which separates a suspended, dissolved, or particulate matter from a fluid, solution, or other substance; any device that separates one substance from another.
  2. Electronics or software that separates unwanted signals (for example noise) from wanted signals or that attenuates selected frequencies.
  3. Any item, mechanism, device, or procedure that acts to separate or isolate.
    He runs an email filter to catch the junk mail.
    • 2013 May 25, “No hiding place”, in The Economist‎[1], volume 407, number 8837, page 74:
      In America alone, people spent $170 billion on “direct marketing”—junk mail of both the physical and electronic varieties—last year. Yet of those who received unsolicited adverts through the post, only 3% bought anything as a result. If the bumf arrived electronically, the take-up rate was 0.1%. And for online adverts the “conversion” into sales was a minuscule 0.01%. That means about $165 billion was spent not on drumming up business, but on annoying people, creating landfill and cluttering spam filters.
  4. (figurative) Self-restraint in speech.
    He's got no filter, and he's always offending people as a result.
  5. (mathematics, order theory) A non-empty upper set (of a partially ordered set) which is closed under binary infima (a.k.a. meets).
    The collection of cofinite subsets of ℝ is a filter under inclusion: it includes the intersection of every pair of its members, and includes every superset of every cofinite set.
    If (1) the universal set (here, the set of natural numbers) were called a "large" set, (2) the superset of any "large" set were also a "large" set, and (3) the intersection of a pair of "large" sets were also a "large" set, then the set of all "large" sets would form a filter.
  6. (photography) A translucent object placed in the light path of a camera to remove certain wavelengths (colors), or a computer program that simulates such an effect.
  7. (social media) an appearance-altering digital image effect
