Electronic Filter

Electronic Filter

Electronic filters are electronic circuits which perform signal processing functions, specifically to remove unwanted frequency components from the signal, to enhance wanted ones, or both. Electronic filters can be:

  • passive or active
  • analog or digital
  • high-pass, low-pass, bandpass, band-reject (band reject; notch), or all-pass.
  • discrete-time (sampled) or continuous-time
  • linear or non-linear
  • infinite impulse response (IIR type) or finite impulse response (FIR type)

The most common types of electronic filters are linear filters, regardless of other aspects of their design. See the article on linear filters for details on their design and analysis.

Famous quotes containing the word electronic:

    The war was won on both sides: by the Vietnamese on the ground, by the Americans in the electronic mental space. And if the one side won an ideological and political victory, the other made Apocalypse Now and that has gone right around the world.
    Jean Baudrillard (b. 1929)
